Given the precipitation of AgCl from a NaCl solution using silver nitrate:
AgNO3 + NaCl(aq) → AgCl(s) + NaNO3(aq)
If a solution of AgNO3 of unknown molarity is added to a flask containing 132ml of NaCl solution also of unknown molarity. At the endpoint 42.15 ml of the AgNO3 solution have been added and 8.42 g of AgCl are recovered as a precipitate from the reaction:
a) What is the molarity of the NaCl solution?
b) What is the molarity of AgNO3 solution?
