### How to Calculate Percent Yield in a Chemical Reaction

The actual yield will always be less than the theoretical yield because no chemical reaction ever reaches 100 percent completion.In a lab setting,theres always some amount of error,whether its big or small.Try an example Calculate the percent yield of sodium sulfate when 32.18 g of sulfuric acid reacts with excess sodium hydroxide to How to Calculate Percent Yield in Chemistry 15 StepsMethodTips Start with a balanced chemical equation .A chemical equation describes the reactants (on the left side) reacting to form products (on the right side).Some problems will give you this equation,while others ask you to write it out yourself,such as for a word problem.Since atoms are not created or destroyed during a chemical reaction,each element should have the same number of atoms on the Calculate the molar mass of each reactant .Look up the molar mass of each atom in the compoundPercent Yield Definition and Formula - ThoughtCoJul 07,2019 How to Calculate Percent Yield in a Chemical Reaction#0183;Usually,you have to calculate the theoretical yield based on the balanced equation.In this equation,the reactant and the product have a 1:1 mole ratio,so if you know the amount of reactant,you know the theoretical yield is the same value in moles (not grams!).You take the number of grams of reactant you have,convert it to moles,and then use this number of moles to find out how many How do you find the percent yield of a chemical reaction To express the efficiency of a reaction,you can calculate the percent yield using this formula %yield = (actual yield/theoretical yield) x 100.A percent yield of 90% means the reaction was 90% efficient,and 10% of the materials were wasted (they failed to react,or their products were not
