10grams of sucrose ÷ 180.15768g/mol sucrose × 2mol ethanol × 6.06904g/mol ethanol ÷ 0.79g/mL
= 6.5 mL ethanol
= 6.5 mL ethanol
sorry there is slight changes. Here is the correct answer
10grams of sucrose ÷ 180.15768g/mol sucrose × 2mol ethanol × 46.06904g/mol ethanol ÷ 0.79g/mL
= 6.5 mL ethanol
10grams of sucrose ÷ 180.15768g/mol sucrose × 2mol ethanol × 46.06904g/mol ethanol ÷ 0.79g/mL
= 6.5 mL ethanol
