Question
Calculate the molar masses of the following substances. Write the results with proper units.
- Ozone molecule, O3
- Ethanoic acid, CH3COOH
Advertisements
Solution
- Molar mass of ozone (O3)
Molar mass of ozone = 16 + 16 +16 = 48 g/mol - Molar mass of acetic acid (CH3COOH)
Molar mass of acetic acid = (2 × 12) + (4 × 1) + (2 × 16) = 60 g/mol
