Methane (CH4, 16.05 g/mol) reacts with oxygen to form carbon dioxide (CO2, 44.01 g/mol) and water (H2O, 18.02 g/mol). Assume that you design a system for converting methane to carbon dioxide and water. To test the efficiency of the system in the laboratory, you burn 5.00 g methane. The actual yield is 6.10 g water. What is your percent yield?

Construct a chemical equation of the process then find the number of mols of water and its mass produced from 5g of methane. This is your theoretical mass of water produced. So divide the mass of water produced in this experiment by the mass of water produced theoretically * 100%
