A 100% yield means that no product has been lost, while a 0 per cent yield means that no product has been made. There are several reasons why the percentage yield of a product might be less than 100 per cent, including loss when: 1  Filtering. 2  Evaporating. 3  Transferring liquids. 4  Not all reactants react to make product.
In chemistry, we have theoretical yield, which is the amount of the product calculated from the limiting reactant. The limiting reactant is the reactant in the chemical reaction which limits the amount of product that can be formed.The actual yield is the actual amount produced when the experiment or reaction is carried out. In calculating the percent yield, we need to calculate the theoretical yield based on the limiting reactant.o use this formula for percent yield, you need to make sure that your actual yield and theoretical yield are in the same units. If the actual yield is in grams, then theoretical yield also needs to be in grams. If theoretical yield is in moles, then the actual yield also needs to be in moles.
