Answer
M(NH4ClO4) ≈
117.49 g/mol
Atomic weights: IUPAC standard values (CIAAW, 2024); the sum is rounded to the decimal places of the least precise one — Cl: 35.45.
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Nnitrogen | 1 | 14.007 | 14.007 w ≈ 11.92% | ≈ 11.92% |
| Hhydrogen | 4 | 1.0080 | 4.0320 w ≈ 3.43% | ≈ 3.43% |
| Clchlorine | 1 | 35.45 | 35.45 w ≈ 30.17% | ≈ 30.17% |
| Ooxygen | 4 | 15.999 | 63.996 w ≈ 54.47% | ≈ 54.47% |
| Σ = 117.485 ≈ 117.49 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%.
