Atomic weights: IUPAC standard values (CIAAW, 2024).
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Nnitrogen | 1 | 14.007 | 14.007 w ≈ 12.18% | ≈ 12.18% |
| Hhydrogen | 6 | 1.0080 | 6.0480 w ≈ 5.26% | ≈ 5.26% |
| Pphosphorus | 1 | 30.974 | 30.974 w ≈ 26.93% | ≈ 26.93% |
| Ooxygen | 4 | 15.999 | 63.996 w ≈ 55.64% | ≈ 55.64% |
| Σ = 115.025 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%.
