A 0.500 g sample of AgCl was mixed with 250 mL sodium chloride solution of unknown molarity. In order to find the molarity of sodium chloride the amount of dissolved silver ion was monitored with an ion selective electrode at 25 C. The electrode registered the concentration of Ag+ ion to be 3.75x10^-8 M. Calculate the concentration of molarity of the NaCl.
