Calculating percentage yield 3.0 / 5 based on 1 rating ? ChemistryCalculations, moles and yieldGCSEAQA Created by: Belle StoreyCreated on: 11-01-13 22:39 What can relative formula mass calculations be used for? finding out how much product should be made (predicted yield) 1 of 5 What happens in actual practice, with predicted yield? its less due to losses in practical methods used 2 of 5 What is formula for percentage yield? percentage yield = actual yield /divided by/ predicted yield times by 100 3 of 5 why do industrial processes need to have a high percentage yield? (1) to reduce the amount of reactants wasted (wasteful and costly) 4 of 5 why do industrial processes need to have a high percentage yield? (2) reduce their costs by ensuring enough reactants are used 5 of 5
