Molar mass calculator
Type a formula - hydrates like CuSO4·5H2O and complexes like K4[Fe(CN)6] too - and get its molar mass with the atomic masses ISC uses (Cl = 35.5, Cu = 63.5), the working, and the percentage of each element.
Answer
- Molar mass of (NH4)2SO4
- 132 g mol⁻¹
Working
| Element | Atoms | Atomic mass | Mass | % by mass |
|---|---|---|---|---|
| H | 8 | 1 | 8 | 6.06 |
| N | 2 | 14 | 28 | 21.21 |
| O | 4 | 16 | 64 | 48.48 |
| S | 1 | 32 | 32 | 24.24 |
Add the masses: 8 + 28 + 64 + 32 = 132 g mol⁻¹.
