Define what fraction of x was precipitated from the solution

Solid, soluble silver nitrate is added slowly to a solution for which the initial concentrations of Cl- and CrO4^-2 were [Cl- ]0 = 0.020 mol L^-1 and [CrO4^-2 ]0 = 0.0050 mol L^-1. (a) Calculate [Ag+] when a precipitate first appears and identify the precipitate. The Ksp values for AgCl(s) and Ag2CrO4(s) are 1.8×10^-10 and 1.1×10^-12, respectively. (b) Calculate [Cl- ] and [CrO4^-2 ] just before the second precipitate is formed. What is the % efficiency of the separation? (i.e. If X represents the anion that precipitates first, then what fraction of X was precipitated from the solution at the instant the second precipitate starts to form?)
