Given that the Atomic Mass Cl: 35.4527 & Atomic Mass Ag: 107.868

To obtain the grams of chloride in a given quantity of AgCl the mass of AgCl is simply multiplied by the ratio of the atomic weight of the chlorine over the molar mass of the AgCl.

Molar mass of AgCl is = 107.868 + 35.4527

= 143.32 g/mol

So mass of chlorine , m = 0.5295 g x ( 35.4527 / 143.32 )

= 0.131 g

% of chlorine = ( mass of chlorine / mass of the sample ) x 100

= ( 0.131 / 0.2254 ) X 100

= 58.12 %

Therefore the percentage of chlorine is 58.12 %
