I synthesized Common Alum in my lab.
KAl(SO4)212H2O(s)
We then had to find the water content based on the initial mass
of the Common Alum subtracted from the anhydrous mass after
heating.
I had 1g of the Common Alum and after heating it, I had 0.57g
and I was able to find the percent of water content: 43%.
1g - 0.57 = 0.43g
0.43g / 1g = 0.43 x 100 = 43%
Now I have to calculate the percentage error...

Alum [KAl(SO4)2·xH2O] is used in food preparation, dye fixation, and water purification. To prepare alum, aluminum is reacted with potassium hydroxide and the product with sulfuric acid. Upon cooling, alum crystallizes from the solution. (a) A 0.4711−g sample of alum is heated to drive off the waters of hydration, and the resulting KAl(SO4)2 weighs 0.2564 g. Determine the value of x and the complete formula of alum. Value of x: Complete Formula: (b) When 0.7339 g of aluminum is used,...
