A Mixture Containing Silver Nitrate (AgNO₃)and Potassium Nitrate (KNO₃), Weighing

A mixture containing silver nitrate (AgNO₃) and potassium nitrate (KNO₃) , weighing 5.000 grams, was dissolved in water and treated with an excess of potassium chloride solution. A quantitative reaction, the reaction of silver nitrate with potassium chloride occurred, and 1.582 grams of a white precipitate, silver chloride, was obtained. Determine the percent, by weight, of silver nitrate in the original mixture. Hint: Use moles as an intermediary when relating different units together.

A) 32.55 %
B) 37.50 %
C) 42.50 %
D) 62.50 %
E) 62.74 %
