= A 0.5099 g mixture of KCN (MW 65.116 g/mol) and NaCN (MW = 49.005 g/mol) was dissolved in water. AgNO, was added to the solution, precipitating all of the CN in solution as AgCN (MW : 133.886 g/mol). The dried precipitate weighed 1.184 g. Calculate the weight percent of KCN and NaCN in the original sample. KCN wt% = NaCN wt% = = % %
