To find the purity of KBr, we need to calculate the percentage of KBr in the 814.5 mg of AgBr obtained. Since AgBr has a molar mass of 187.77 g/mol and KBr has a molar mass of 119 g/mol, we can find that the molar ratio of KBr to AgBr is 119/187.77. Then we can calculate the purity as (119/187.77) * (814.5/532.1) * 100%.
