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
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.
