| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Ccarbon | 4 | 12.011 | 48.044 w ≈ 39.66% | ≈ 39.66% |
| Hhydrogen | 11 | 1.0080 | 11.0880 w ≈ 9.15% | ≈ 9.15% |
| Nnitrogen | 1 | 14.007 | 14.007 w ≈ 11.56% | ≈ 11.56% |
| Ooxygen | 3 | 15.999 | 47.997 w ≈ 39.62% | ≈ 39.62% |
| Σ = 121.136 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%.
