How 208.230 g/mol is worked out
| Element | Atoms | Atomic mass | Mass | % of total |
|---|---|---|---|---|
| Barium | 1 | 137.33 | 137.330 | 65.95% |
| Chlorine | 2 | 35.45 | 70.900 | 34.05% |
| Total | 3 | 208.230 | 100% |
M = 1 × 137.330 + 2 × 35.450 = 208.230 g/mol

Frequently Asked Questions
What is the molar mass of Barium chloride?
The molar mass of Barium chloride (BaCl2) is 208.230 g/mol. That is the sum of the standard atomic weights of all 3 atoms in one formula unit: 1 × 137.330 + 2 × 35.450 = 208.230.
What is the molecular weight of Barium chloride?
208.230 — 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 208.23 and a molar mass of 208.23 g/mol are the same answer.
How many moles are in 100 g of Barium chloride?
100 ÷ 208.230 = 0.4802 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Barium chloride?
By mass, Barium chloride is 65.95% barium, 34.05% chlorine. Each element's share is its total mass in the formula divided by 208.230.
How many atoms are in one formula unit of Barium chloride?
3: 1 barium, 2 chlorine. One mole contains 6.02214076 × 10²³ formula units, so a mole of Barium chloride contains 3 × 6.022 × 10²³ atoms in total.
