How 102.894 g/mol is worked out
| Element | Atoms | Atomic mass | Mass | % of total |
|---|---|---|---|---|
| Bromine | 1 | 79.904 | 79.904 | 77.66% |
| Sodium | 1 | 22.99 | 22.990 | 22.34% |
| Total | 2 | 102.894 | 100% |
M = 1 × 79.904 + 1 × 22.990 = 102.894 g/mol

Frequently Asked Questions
What is the molar mass of Sodium bromide?
The molar mass of Sodium bromide (NaBr) is 102.894 g/mol. That is the sum of the standard atomic weights of all 2 atoms in one formula unit: 1 × 79.904 + 1 × 22.990 = 102.894.
What is the molecular weight of Sodium bromide?
102.894 — 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 102.89 and a molar mass of 102.89 g/mol are the same answer.
How many moles are in 100 g of Sodium bromide?
100 ÷ 102.894 = 0.9719 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 bromide?
By mass, Sodium bromide is 77.66% bromine, 22.34% sodium. Each element's share is its total mass in the formula divided by 102.894.
How many atoms are in one formula unit of Sodium bromide?
2: 1 bromine, 1 sodium. One mole contains 6.02214076 × 10²³ formula units, so a mole of Sodium bromide contains 2 × 6.022 × 10²³ atoms in total.
