25.0 mL of a NaCl solution (concentration unknown) was found to react with 20 drops of the chloride test solution from the PU Chloride Test Kit.
Calculate the mass of NaCl (in grams) in this solution.
Calculate the mass of NaCl required to prepare 0.250 L of a NaCl solution with the same concentrations.
