First we have to calculate Molecular mass of BaSO4 which is 233 g/mol...... now 233 g BaSO4 contain 32 g of sulphur..... therefore 0.4813 BaSO4 contain ➡️32 /233× 0.4813 g of sulphur.... nd by calculating above eq. u get 0.066g of sulphur .... now find we have to find %of sulphur.. so % = 0.066/0.157 ×100 = 42.1%.......
