6.7 mL of a ptassium chlorid solution was added to a 54.730 gevaporating dish. The combination weight 61.945 g. Afterevaporation the dish contents weight 55.428 g.

a. What was the mass percent of potassium chloride in thesolution?
b. If the actual mass percent of the potassium in the abovesolution was 10.00%, what was the percentage error of the abovemeasurment?
c. Why was the evaporation used to determine the masspercentage of potassium cloride in the solution rather than thefiltration or recrystallization? Explain.
