C60 molecule<\/a><\/strong> mass is calculated from the molar mass of Fullerene C60<\/a> and Avogadro\u2019s constant. The short answer is:<\/p>\n\n\n\n

The mass of one molecule of C60 is approximately 1.20 \u00d7 10-21<\/sup> grams, or 1.20 \u00d7 10-24<\/sup> kilograms.<\/strong><\/p>\n\n\n\n

This value comes from a simple conversion. Fullerene C60<\/a> has the molecular formula C60, meaning one C60 molecule contains 60 carbon atoms. Its molar mass is about 720.66 g\/mol, and one mole contains 6.02214076 \u00d7 1023<\/sup> molecules.[1]<\/a><\/sup>[2]<\/a><\/sup><\/p>\n\n\n\n

What Is a C60 Molecule?<\/h2>\n\n\n\n

A C60 molecule is a fullerene molecule made of 60 carbon atoms arranged in a closed cage. It is also called Fullerene C60, buckminsterfullerene, Carbon 60, or buckyball.<\/p>\n\n\n\n

The name \u201cC60\u201d comes directly from its formula: C means carbon, and 60 means there are 60 carbon atoms in one molecule.<\/p>\n\n\n\n

PubChem identifies Fullerene C60 with molecular formula C60 and molecular weight around 720.6 g\/mol.[3]<\/a><\/sup> Fisher Scientific lists Fullerene C60 under CAS number 99685-96-8, molecular formula C60, and molecular weight 720.66 g\/mol.[1]<\/a><\/sup><\/p>\n\n\n\n

Structurally, the C60 molecule is often compared to a soccer ball. It is a spherical carbon cage made from pentagons and hexagons. This shape is why C60 is known as buckminsterfullerene, named after architect R. Buckminster Fuller, whose geodesic dome designs resemble the geometry of the molecule.<\/p>\n\n\n\n

How to Calculate the Mass of One Molecule of C60<\/h2>\n\n\n\n

The calculation has three steps.<\/p>\n\n\n\n

\"\"
<\/figcaption><\/figure>\n\n\n\n

Step 1: Find the molar mass of C60<\/h3>\n\n\n\n

A C60 molecule contains 60 carbon atoms. The atomic weight of carbon is about 12.011 g\/mol according to IUPAC\u2019s standard atomic weight table.[4]<\/a><\/sup><\/p>\n\n\n\n

So the approximate molar mass is:<\/p>\n\n\n\n

60 \u00d7 12.011 g\/mol = 720.66 g\/mol<\/strong><\/p>\n\n\n\n

This matches commonly listed Fullerene C60 molecular weight values.<\/p>\n\n\n\n

Step 2: Use Avogadro\u2019s constant<\/h3>\n\n\n\n

Avogadro\u2019s constant tells us how many molecules are in one mole:<\/p>\n\n\n\n

6.02214076 \u00d7 1023<\/sup> molecules\/mol<\/strong><\/p>\n\n\n\n

NIST lists this value as exact.[2]<\/a><\/sup><\/p>\n\n\n\n

Step 3: Divide molar mass by Avogadro\u2019s constant<\/h3>\n\n\n\n

To find the mass of one C60 molecule:<\/p>\n\n\n\n

Mass of one C60 molecule = 720.66 \u00f7 6.02214076 \u00d7 1023<\/sup><\/strong><\/p>\n\n\n\n

This gives:<\/p>\n\n\n\n

1.1967 \u00d7 10-21<\/sup> g<\/strong><\/p>\n\n\n\n

So the mass of one molecule of C60 is approximately 1.20 \u00d7 10-21<\/sup> grams<\/strong>.<\/p>\n\n\n\n

Why C60 Has a Molar Mass of About 720.66 g\/mol<\/h2>\n\n\n\n

The molar mass of a C60 molecule is easy to understand once the formula is clear. C60 contains 60 carbon atoms. Each carbon atom contributes about 12.011 g\/mol to the molar mass.<\/p>\n\n\n\n

The calculation is:<\/p>\n\n\n\n

60 \u00d7 12.011 = 720.66 g\/mol<\/strong><\/p>\n\n\n\n

This does not mean that one C60 molecule weighs 720.66 grams. It means that one mole of C60 molecules weighs about 720.66 grams.<\/p>\n\n\n\n

One mole is a very large number of particles: 6.02214076 \u00d7 1023<\/sup>. That is why the mass of one individual C60 molecule is extremely small.<\/p>\n\n\n\n

Molecular Mass vs Molar Mass of C60<\/h2>\n\n\n\n

When discussing the C60 molecule, it is important to separate molecular mass from molar mass.<\/p>\n\n\n\n

Term<\/th>Meaning<\/th>Value for C60<\/th><\/tr><\/thead>
Molecular formula<\/td>Atoms in one molecule<\/td>C60<\/td><\/tr>
Molecular mass<\/td>Mass of one molecule<\/td>About 1.20 \u00d7 10-21<\/sup> g<\/td><\/tr>

The common mistake is to say \u201cone C60 molecule has a mass of 720.66 g.\u201d That is incorrect. 720.66 g is the mass of one mole of C60 molecules, not one molecule.<\/p>\n\n\n\n

What Is the Mass of One Molecule of C60 in Kilograms?<\/h2>\n\n\n\n

The mass of one C60 molecule in grams is approximately:<\/p>\n\n\n\n

1.1967 \u00d7 10-21<\/sup> g<\/strong><\/p>\n\n\n\n

To convert grams to kilograms, divide by 1000:<\/p>\n\n\n\n

1.1967 \u00d7 10-21<\/sup> g = 1.1967 \u00d7 10-24<\/sup> kg<\/strong><\/p>\n\n\n\n

Rounded to three significant figures:<\/p>\n\n\n\n

1.20 \u00d7 10-24<\/sup> kg per C60 molecule<\/strong><\/p>\n\n\n\n

How Many C60 Molecules Are in 1 Gram?<\/h2>\n\n\n\n

Another useful question is how many C60 molecules are in 1 gram of Fullerene C60.<\/p>\n\n\n\n

First, convert 1 gram of C60 into moles:<\/p>\n\n\n\n

1 g \u00f7 720.66 g\/mol = 0.0013876 mol<\/strong><\/p>\n\n\n\n

Then multiply by Avogadro\u2019s constant:<\/p>\n\n\n\n

0.0013876 \u00d7 6.02214076 \u00d7 1023<\/sup> = 8.36 \u00d7 1020<\/sup> molecules<\/strong><\/p>\n\n\n\n

So, 1 gram of C60 contains approximately 8.36 \u00d7 1020<\/sup> C60 molecules<\/strong>.<\/p>\n\n\n\n

This helps explain why laboratory quantities of C60 may look small by mass but still contain an enormous number of molecules.<\/p>\n\n\n\n

How Many Moles Are in 1 Gram of C60?<\/h2>\n\n\n\n

The number of moles in 1 gram of C60 is calculated by dividing sample mass by molar mass:<\/p>\n\n\n\n

1 g \u00f7 720.66 g\/mol = 0.0013876 mol<\/strong><\/p>\n\n\n\n

This is about:<\/p>\n\n\n\n

1.39 \u00d7 10-3<\/sup> mol<\/strong><\/p>\n\n\n\n

or:<\/p>\n\n\n\n

1.39 mmol<\/strong><\/p>\n\n\n\n

This conversion is useful when preparing solutions, comparing molar ratios, or calculating reaction quantities involving Fullerene C60.<\/p>\n\n\n\n

Why This Calculation Matters<\/h2>\n\n\n\n

The mass of one C60 molecule matters because it connects molecular-scale chemistry with practical laboratory quantities. A chemist may need this value to calculate molecule numbers, molar concentration, film deposition amount, or reaction stoichiometry.<\/p>\n\n\n\n

For example, if a researcher prepares a C60 solution, the mass weighed on a laboratory balance must be converted into moles or molecules. If a thin-film researcher deposits C60 onto a substrate, molecular mass and molar mass may help interpret material loading or deposition calculations.<\/p>\n\n\n\n

For students, this calculation is also a clean example of how molar mass and Avogadro\u2019s constant connect microscopic particles to measurable laboratory mass.<\/p>\n\n\n\n

Common Mistakes When Calculating C60 Molecule Mass<\/h2>\n\n\n\n

Mistake 1: Confusing molar mass with molecular mass<\/h3>\n\n\n\n

720.66 g\/mol is the molar mass of C60. It is not the mass of one molecule. The mass of one molecule is about 1.20 \u00d7 10-21<\/sup> g.<\/p>\n\n\n\n

Mistake 2: Using 60 g\/mol as the molar mass<\/h3>\n\n\n\n

The \u201c60\u201d in C60 means there are 60 carbon atoms, not that the molar mass is 60 g\/mol. Since each carbon atom contributes about 12.011 g\/mol, the molar mass is about 720.66 g\/mol.<\/p>\n\n\n\n

Mistake 3: Forgetting Avogadro\u2019s constant<\/h3>\n\n\n\n

To move from molar mass to the mass of one molecule, Avogadro\u2019s constant must be used. Without it, the calculation stops at grams per mole rather than grams per molecule.<\/p>\n\n\n\n

Mistake 4: Overstating precision<\/h3>\n\n\n\n

For most practical purposes, 1.20 \u00d7 10-21<\/sup> g is enough. More digits may be used in formal calculations, but the value is still an approximation when standard atomic weights and rounded molar masses are used.<\/p>\n\n\n\n

Light Product Note<\/h2>\n\n\n\n

If you are comparing C60 molecule data for research or sourcing purposes, product identity should match the formula C60, CAS number 99685-96-8, and the expected molar mass of approximately 720.66\u2013720.67 g\/mol. You can review Fullerene C60 product information<\/a> or contact The Fullerene<\/a> for material details when needed.<\/p>\n\n\n\n

FAQ<\/h2>\n\n\n\n
