The amount of sodium chloride in the original mixture can be determined indirectly by subtracting the masses of ammonium chloride and sand from the initial mass of the powdered mixture. Calculate the percent difference between the results from the two methods using the following equation % difference = |(measured mass) − (mass by subtraction)| / (mass by subtraction) × 100%
