How 34.076 g/mol is worked out
| Element | Atoms | Atomic mass | Mass | % of total |
|---|---|---|---|---|
| Sulfur | 1 | 32.06 | 32.060 | 94.08% |
| Hydrogen | 2 | 1.008 | 2.016 | 5.92% |
| Total | 3 | 34.076 | 100% |
M = 1 × 32.060 + 2 × 1.008 = 34.076 g/mol

Frequently Asked Questions
What is the molar mass of Hydrogen sulfide?
The molar mass of Hydrogen sulfide (H2S) is 34.076 g/mol. That is the sum of the standard atomic weights of all 3 atoms in one formula unit: 1 × 32.060 + 2 × 1.008 = 34.076.
What is the molecular weight of Hydrogen sulfide?
34.076 — 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 34.08 and a molar mass of 34.08 g/mol are the same answer.
How many moles are in 100 g of Hydrogen sulfide?
100 ÷ 34.076 = 2.9346 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Hydrogen sulfide?
By mass, Hydrogen sulfide is 94.08% sulfur, 5.92% hydrogen. Each element's share is its total mass in the formula divided by 34.076.
How many atoms are in one formula unit of Hydrogen sulfide?
3: 1 sulfur, 2 hydrogen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Hydrogen sulfide contains 3 × 6.022 × 10²³ atoms in total.
