Molar Mass Calculator
What is the molar mass of Ca(OH)2?
Answer
M(Ca(OH)2) =
74.092 g/mol
Atomic weights: IUPAC standard values (CIAAW, 2024).
Ca(OH)2 = Ca + 2 × (O + H) → Ca 1, O 2, H 2
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Cacalcium | 1 | 40.078 | 40.078 w ≈ 54.09% | ≈ 54.09% |
| Ooxygen | 2 | 15.999 | 31.998 w ≈ 43.19% | ≈ 43.19% |
| Hhydrogen | 2 | 1.0080 | 2.0160 w ≈ 2.72% | ≈ 2.72% |
| Σ = 74.092 g/mol w = 100% | 100% | |||
