Why is percent yield low

Usually, you have to calculate the theoretical yield based on the balanced equation. In this equation, the reactant and the product have a 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 grams of product to expect.

What is the theoretical yield of oxygen gas? What is the percent yield for the reaction? First, we will calculate the theoretical yield based on the stoichiometry. Step 1: List the known quantities and plan the problem. Apply stoichiometry to convert from the mass of a reactant to the mass of a product:.

Now we will use the actual yield and the theoretical yield to calculate the percent yield. Percent Yield Chemical reactions in the real world do not always go exactly as planned on paper. Solution First, we will calculate the theoretical yield based on the stoichiometry. Step 3: Think about your result.
