8- When a sample of impure potassium chloride (0.4500g) was dissolved in water and treated with an excess of silver nitrate, 0.8402 g of silver chloride was precipitated. Calculate the percentage KCI in the original sample. (Answer: 97.12 %) Sample=0.450 g AgCl = 0.8402 g KCI + AgNO3 MM KCI=74.55 g/mol MM AgCl = 143.32 g/mol AgCI + KNO3
