Homework Answers
1 mole of sucrose gives 4 moles of ethanol.
Number of moles = mass/molar mass
Molar mass of sucrose = 342.30 g/mol
Molar mass of ethanol = 46.07 g/mol
Moles of sucrose = 2.02/342.30
= 0.0059 moles
Moles of ethanol formed = 0.0059 × 4
= 0.0236 moles
Mass of ethanol formed = 0.0236 × 46.07
= 1.09 grams ethanol

The sucrose (C12H22011) in sugarcane can react with with water to produce ethanol (C2HO) and carbon dioxide. In this way, sugarcane can be used as a renewable source of ethanol, which is used for a fuel additive in gasoline. If you had 312.9 grams of sucrose and reacted with excess water, how many mL of ethanol could be produced? The density of ethanol is 0.789 g/mL.
