Molar Mass Calculator
What is the molar mass of Co(NO3)2?
Answer
M(Co(NO3)2) =
182.941 g/mol
Atomic weights: IUPAC standard values (CIAAW, 2024).
Co(NO3)2 = Co + 2 × (N + 3 O) → Co 1, N 2, O 6
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Cocobalt | 1 | 58.933 | 58.933 w ≈ 32.21% | ≈ 32.21% |
| Nnitrogen | 2 | 14.007 | 28.014 w ≈ 15.31% | ≈ 15.31% |
| Ooxygen | 6 | 15.999 | 95.994 w ≈ 52.47% | ≈ 52.47% |
| Σ = 182.941 g/mol w = 100% | 100% | |||
Each fraction is rounded on its own, so the printed ones add up to 99.99%; unrounded, they make exactly 100%.
