How 180.156 g/mol is worked out
| Element | Atoms | Atomic mass | Mass | % of total |
|---|---|---|---|---|
| Oxygen | 6 | 15.999 | 95.994 | 53.28% |
| Carbon | 6 | 12.011 | 72.066 | 40.00% |
| Hydrogen | 12 | 1.008 | 12.096 | 6.71% |
| Total | 24 | 180.156 | 100% |
M = 6 × 15.999 + 6 × 12.011 + 12 × 1.008 = 180.156 g/mol

Frequently Asked Questions
What is the molar mass of Glucose?
The molar mass of Glucose (C6H12O6) is 180.156 g/mol. That is the sum of the standard atomic weights of all 24 atoms in one formula unit: 6 × 15.999 + 6 × 12.011 + 12 × 1.008 = 180.156.
What is the molecular weight of Glucose?
180.156 — the same number as the molar mass, but as a dimensionless ratio rather than in g/mol. The two terms describe the same arithmetic, so a molecular weight of 180.16 and a molar mass of 180.16 g/mol are the same answer.
How many moles are in 100 g of Glucose?
100 ÷ 180.156 = 0.5551 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Glucose?
By mass, Glucose is 53.28% oxygen, 40.00% carbon, 6.71% hydrogen. Each element's share is its total mass in the formula divided by 180.156.
How many atoms are in one formula unit of Glucose?
24: 6 oxygen, 6 carbon, 12 hydrogen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Glucose contains 24 × 6.022 × 10²³ atoms in total.
