# Problem: The combustion of liquid ethanol (C2 H5 OH) produces carbon dioxide and water. After 4.63 mL of ethanol (density = 0.789/ml) was allowed to burn in the presence of 15.60 g of oxygen gas, 3.73 mL of water (density = 1.00/ml) was collected.Determine the limiting reactant for the reaction. (Hint: Write a balanced equation for the combustion of ethanol.)

###### FREE Expert Solution

We are asked to determine the limiting reactant for the reaction.

Balance reaction:

C2H5OH  + 3 O2→ 2 CO2 + 3 H2O

Molar mass C2H5OH = 46.08 g/mol

Molar mass O2 = 32.0 g/mol

Molar mass H2O =18.02 g/mol
