Element | Total atoms | Atomic mass | Total mass |
---|---|---|---|
C (Carbon) | 7 | 12.0107 | 84.0749 |
H (Hydrogen) | 6 | 1.00794 | 6.04764 |
O (Oxygen) | 2 | 15.9994 | 31.9988 |
122.12134 |
- Mr[C6H5COOH] = Ar[C] * 7 + Ar[H] * 6 + Ar[O] * 2 = 12.0107 * 7 + 1.00794 * 6 + 15.9994 * 2 = 122.12134
- Molar mass (kg/mol) = Mr[C6H5COOH] : 1000 = 122.12134 : 1000 = 0.12212 kg/mol
- Carbon (C) = 84.0749 : 122.12134 * 100 = 68.845 %
- Hydrogen (H) = 6.04764 : 122.12134 * 100 = 4.952 %
- Oxygen (O) = 31.9988 : 122.12134 * 100 = 26.202 %
