An impure silver sample weighing 0.1652g reacts with diluted HNO3, forming the add HCl, a white precipitate that weighed 0.0911 g of silver chloride. What degree of purity of silver in the sample?
1 mol Ag will give you 1 mol AgNO3 which will give 2 mol AgCl. Convert grams AgCl to grams Ag. mm = molar mass; am = atomic mass.
grans AgCl x (am Ag/mm AgCl) = ?
Then % Ag = (mass Ag/mass sample)*100 = ?
