A 0.6888 g mixture of KCN ( MW=65.116 g/mol ) and NaCN ( MW=49.005 g/mol ) was dissolved in water. AgNO3 was added to the solution, precipitating all of the CN− in solution as AgCN ( MW=133.886 g/mol ). The dried precipitate weighed 1.556 g. Calculate the weight percent of KCN and NaCN in the original sample.
