A chemistry student needs to determine the effect of adding NaCl to a solution containing AgNO3 at equilibrium. The original solution had concentration [Ag+]=0.01M and [NO3-]=0.01M, and Ksp=1.8x10^-10. How much NaCl (in grams) is needed to be added to the solution in order to decrease the [Ag+] concentration by a factor of 10?
