#caie #chemistry #ahmedbokhari This video shows you how to calculate the theoretical and percent yield in O level and IGCSE chemistry. The theoretical yield is the maximum amount of product that can be produced in a reaction. The percent yield is equal to the actual yield divided by the theoretical yield times 100%.
It also discusses percetnage purity which is how much of the pure substance is present in an impure sample.
