Atomic weights: IUPAC standard values (CIAAW, 2024).
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Ccarbon | 2 | 12.011 | 24.022 w ≈ 38.70% | ≈ 38.70% |
| Hhydrogen | 6 | 1.0080 | 6.0480 w ≈ 9.74% | ≈ 9.74% |
| Ooxygen | 2 | 15.999 | 31.998 w ≈ 51.55% | ≈ 51.55% |
| Σ = 62.068 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%.
