This "person" makes a practice of asking difficult chemistry questions and then deleting the question the instant she recieves her first reasonable answer. This leaves the rest of us, who have also solved her problem just twisting in the wind. She gets multiple fools like us to do her homework for her and she never even has to be reminded of our existence. If you click on her avatar, you'll discover she doesn't accept emails. Thus, there's no way to give this thoughtless chick the flame-job she deserves.

Al2(SO4)3•18H2O is used to help dyes adhere to clothes. One way to make this compound is represented in the following equation. You must report your answers to the correct number of significant figures.
Al(OH)3 + H2SO4 + H2O → Al2(SO4)3•18H2O

a) Balance this equation
b) Determine the maximum yield of Al2(SO4)3•18H2O that could be obtained by starting with 25.0 g Al(OH)3, 50.0 g H2SO4 and unlimited water.

c) If 3.2 g of Al2(SO4)3•18H2O form, what is the percent yield for this reaction?
