# Problem: The combustion of liquid ethanol (C2 H5 OH) produces carbon dioxide and water. After 4.63 mL of ethanol (density = 0.789g/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 percent yield of H2 O for the reaction.

We’re being asked to calculate the percent yield of H2O in the combustion of liquid ethanol.

Recall that percent yield is given by:

We will determine the theoretical yield of H2O then its percent yield.

For this problem, we need to do the following steps:

Step 1: Write and balance a chemical equation for the given reaction.

Step 2: Determine the moles of each reactant

Step 3: Determine the limiting reactant and actual yield of H2O.

Step 4: Calculate the percent yield of H2O
