Problem
A 0.150 g sample of a soluble chloride salt is treated with excess AgNO₃(aq), forming a precipitate according to the net ionic reaction
Ag⁺(aq) + Cl⁻(aq) → AgCl(s)
After filtration and drying, 0.192 g of AgCl is obtained. Calculate the percent by mass of chloride ion in the original sample.
