Questiоn 17: The cоncentrаtiоn of аrsenic in аn insecticide is determined gravimetrically by precipitating it as MgNH4AsO4 and isolating it as Mg2As2O7. Determine the %w/w As2O3 in a 2.667-g sample of insecticide if it yields 97.5 mg of Mg2As2O7. (Formula weights: MgNH4AsO4 = 181.26 g/mol; Mg2As2O7 = 310.45 g/mol; As2O3 = 197.84 g/mol)
