William measures a test tube and finds that the mass of the test tube is 5g. He places the lone reactant in the test tube and finds the mass to be 12.5g. He carries out a reaction by heating the test tube. At the end of the reaction, he measures the mass of the test tube containing the lone product and finds it to have a mass of 9.3g. What is the percent yield for this experiment if he expected to produce 5g of product?
