100mL of a 0.100M solution of NaCl is prepared (standard solution). This solution will be used to standardize a AgNO3 solution. Since the concentration of AgNO3 changes slightly with time, it has to be standardized. The exact concentration of AgNO3 is determined using the 0.100M NaCl solution. Calculate the mass of NaCl that is necessary to prepare the standard solution.
