Molar Mass Calculator
What is the molar mass of HCl?
Answer
M(HCl) ≈
36.46 g/mol
Atomic weights: IUPAC standard values (CIAAW, 2024); the sum is rounded to the decimal places of the least precise one — Cl: 35.45.
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Hhydrogen | 1 | 1.0080 | 1.0080 w ≈ 2.76% | ≈ 2.76% |
| Clchlorine | 1 | 35.45 | 35.45 w ≈ 97.24% | ≈ 97.24% |
| Σ = 36.458 ≈ 36.46 g/mol w = 100% | 100% | |||
Atomic weights: CIAAW, Abridged Standard Atomic Weights (2024)
Cl 97.24%
H 2.76%
