A 500-gram sample of Al2(SO4)3 is reacted with 400 g of Ca(OH)2. A total of 596 g of CaSO4 is produced. What is the limiting reagent in this reaction and how many moles of excess reagent are unreacted? Al(SO4)3(aq) + 3Ca(OH)2(aq) --> 2Al(OH)3(s) + 3CaSO4(s) This is what I have so far: 450/1 x 1/74 =...
