What mass of CO2 is produced by oxidizing 1.0 g of benzaldehyde to benzoic acid? (Molar masses: C7H6O = 106 g/mol, CO2 = 44 g/mol)
Q1. What mass of CO2 is produced by oxidizing 1.0 g of benzaldehyde to benzoic acid? (Molar masses: C7H6O = 106 g/mol, CO2 = 44 g/mol)
Answer: 0.41 g
Explanation: 1 mole aldehyde produces 1 mole CO2. 1.0 g / 106 g/mol = 0.00943 mol. 0.00943 × 44 = 0.41 g (B assumes CO2 molar mass = 30).
