how to calculate theoretical percent yield. To calculate the theoretical percentage of an element in a compound divide the molar mass of the element by the mass of the compound and multiply by 100. Yield actual yieldtheoretical yield x 100.
The percentage yield can be calculated using the mass of the actual product obtained and the theoretical mass of the product calculated using the balanced equation of the reaction. It indicates the percent of theoretical yield that was obtained from the final product in an experiment. In this video I answer these two questions.
Select the reactant that has the lowest number of moles when stoichiometry is taken into account.
To calculate a full percentage take the decimal results from the above step and multiply it by 100. Theoretical yield is calculated based on the stoichiometry of the chemical equation. 2H 2 O 2 2H 2 O O 2. Here we have to convert and express the given mass in grams.
