How 44.013 g/mol is worked out
| Element | Atoms | Atomic mass | Mass | % of total |
|---|---|---|---|---|
| Nitrogen | 2 | 14.007 | 28.014 | 63.65% |
| Oxygen | 1 | 15.999 | 15.999 | 36.35% |
| Total | 3 | 44.013 | 100% |
M = 2 × 14.007 + 1 × 15.999 = 44.013 g/mol

Frequently Asked Questions
What is the molar mass of Nitrous oxide?
The molar mass of Nitrous oxide (N2O) is 44.013 g/mol. That is the sum of the standard atomic weights of all 3 atoms in one formula unit: 2 × 14.007 + 1 × 15.999 = 44.013.
What is the molecular weight of Nitrous oxide?
44.013 — 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 44.01 and a molar mass of 44.01 g/mol are the same answer.
How many moles are in 100 g of Nitrous oxide?
100 ÷ 44.013 = 2.2721 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Nitrous oxide?
By mass, Nitrous oxide is 63.65% nitrogen, 36.35% oxygen. Each element's share is its total mass in the formula divided by 44.013.
How many atoms are in one formula unit of Nitrous oxide?
3: 2 nitrogen, 1 oxygen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Nitrous oxide contains 3 × 6.022 × 10²³ atoms in total.
