AI Generated Solution

To determine how much energy will be liberated when 3.42 g of sucrose (C₁₂H₂₂O₁₁) is burnt, we can follow these steps: ### Step 1: Calculate the molar mass of sucrose (C₁₂H₂₂O₁₁) - The molar mass is calculated using the atomic masses of carbon (C), hydrogen (H), and oxygen (O). - Molar mass of sucrose = (12 × atomic mass of C) + (22 × atomic mass of H) + (11 × atomic mass of O) - Atomic mass of C = 12 g/mol, H = 1 g/mol, O = 16 g/mol. **Calculation:** ...
