Molar Mass Calculator
What is the molar mass of Fe(OH)2?
Answer
M(Fe(OH)2) =
89.859 g/mol
Atomic weights: IUPAC standard values (CIAAW, 2024).
Fe(OH)2 = Fe + 2 × (O + H) → Fe 1, O 2, H 2
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Feiron | 1 | 55.845 | 55.845 w ≈ 62.15% | ≈ 62.15% |
| Ooxygen | 2 | 15.999 | 31.998 w ≈ 35.61% | ≈ 35.61% |
| Hhydrogen | 2 | 1.0080 | 2.0160 w ≈ 2.24% | ≈ 2.24% |
| Σ = 89.859 g/mol w = 100% | 100% | |||
