Atomic weights: IUPAC standard values (CIAAW, 2024).
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Ccarbon | 8 | 12.011 | 96.088 w ≈ 64.87% | ≈ 64.87% |
| Hhydrogen | 4 | 1.0080 | 4.0320 w ≈ 2.72% | ≈ 2.72% |
| Ooxygen | 3 | 15.999 | 47.997 w ≈ 32.40% | ≈ 32.40% |
| Σ = 148.117 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%.
