Calculating Molecular Mass
Acetic acid consists of:
- 2 Carbon (C) atoms: 2 × 12.01 g/mol = 24.02 g/mol
- 4 Hydrogen (H) atoms: 4 × 1.008 g/mol = 4.032 g/mol
- 2 Oxygen (O) atoms: 2 × 16.00 g/mol = 32.00 g/mol
Total Molecular Mass
Now, add these values together:
Total = 24.02 + 4.032 + 32.00 = 60.052 g/mol
Therefore, the molecular mass of acetic acid is approximately 60.05 g/mol, and this value does not change when it is dissolved in benzene or any other solvent.
