Atomic weights: IUPAC standard values (CIAAW, 2024).
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Ccarbon | 3 | 12.011 | 36.033 w ≈ 40.44% | ≈ 40.44% |
| Hhydrogen | 7 | 1.0080 | 7.0560 w ≈ 7.92% | ≈ 7.92% |
| Nnitrogen | 1 | 14.007 | 14.007 w ≈ 15.72% | ≈ 15.72% |
| Ooxygen | 2 | 15.999 | 31.998 w ≈ 35.91% | ≈ 35.91% |
| Σ = 89.094 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%.
