Asked by Jon
A 1.85-g sample of a mixture of KCl and MgCl(subscript 2) is treated with excess AgNO(subscript 3) (aq). If 3.82 grams of AgCl(s) are obtained, then what is the percentage by mass of KCl in the original mixture.
Can someone tell me what the balanced chemical equation is for this reaction please?

Chloride comes from two sources.
AgNO3 + KCl ==> AgCl + KNO3 AND
2AgNO3 + MgCl2 --> 2AgCl + Mg(NO3)2
To solve this problem you must have two equations and solve them simultaneously.
