AI Generated Solution

To calculate the percentage of carbon and hydrogen in the organic compound, we can follow these steps: ### Step 1: Calculate the mass of carbon from CO₂ 1. **Determine the moles of CO₂ produced**: - The molar mass of CO₂ = 12 (C) + 16*2 (O) = 44 g/mol - Moles of CO₂ = mass of CO₂ / molar mass of CO₂ \[ \text{Moles of CO₂} = \frac{0.5764 \text{ g}}{44 \text{ g/mol}} = 0.0131 \text{ mol} ...
