To calculate a percentage yield in chemistry start with a balanced chemical equation with the reactants on the left side and the products on the right. Multiply the number of moles of water by the molar mass of water. The theoretical yield is known to be 15 grams.
Assume that none of the substances were wasted during the process and no by-products are produced then your percent yield is 100 percent which is almost impossible to achieve.
Should be in your lab notes. 1 The combustion of 0374 kg of methane in the presence of excess oxygen produces 0983 kg of carbon dioxide. 6Li s N2. Ratio of Actual to Theoretical Yield.
