Calculate and record the following quantities.
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:
How is this lab using the difference in the physical properties of the powdered mixture
components to separate them? What is the mass percent of iron in the mixture?
