| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Ccarbon | 12 | 12.011 | 144.132 w ≈ 36.25% | ≈ 36.25% |
| Hhydrogen | 19 | 1.0080 | 19.1520 w ≈ 4.82% | ≈ 4.82% |
| Clchlorine | 3 | 35.45 | 106.35 w ≈ 26.75% | ≈ 26.75% |
| Ooxygen | 8 | 15.999 | 127.992 w ≈ 32.19% | ≈ 32.19% |
| Σ = 397.626 ≈ 397.63 g/mol w = 100% | 100% | |||
Each fraction is rounded on its own, so the printed ones add up to 100.01%; unrounded, they make exactly 100%.
