How 41.988 g/mol is worked out
| Element | Atoms | Atomic mass | Mass | % of total |
|---|---|---|---|---|
| Sodium | 1 | 22.99 | 22.990 | 54.75% |
| Fluorine | 1 | 18.998 | 18.998 | 45.25% |
| Total | 2 | 41.988 | 100% |
M = 1 × 22.990 + 1 × 18.998 = 41.988 g/mol

Frequently Asked Questions
What is the molar mass of Sodium fluoride?
The molar mass of Sodium fluoride (NaF) is 41.988 g/mol. That is the sum of the standard atomic weights of all 2 atoms in one formula unit: 1 × 22.990 + 1 × 18.998 = 41.988.
What is the molecular weight of Sodium fluoride?
41.988 — 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 41.99 and a molar mass of 41.99 g/mol are the same answer.
How many moles are in 100 g of Sodium fluoride?
100 ÷ 41.988 = 2.3816 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Sodium fluoride?
By mass, Sodium fluoride is 54.75% sodium, 45.25% fluorine. Each element's share is its total mass in the formula divided by 41.988.
How many atoms are in one formula unit of Sodium fluoride?
2: 1 sodium, 1 fluorine. One mole contains 6.02214076 × 10²³ formula units, so a mole of Sodium fluoride contains 2 × 6.022 × 10²³ atoms in total.
