consider the reaction, 2Al(OH)3+3H2SO4---->Al2(SO4)3+6H2O a. Given that 152g of H2SO4 reacts with 234g of Al(OH)3 Howmany grams of Al2(SO4)3 will be theoretical generated? b. which of the reactants is the limiting reagent? c. If the actuall yield was 135 g Al(SO4)3, what is the percent yield?

    I solve these limiting reagent problems by solving two simple stoichiometry problems, the first time with one reagent, the second time with the other reagent. The one providing the SMALLEST number of moles for the product will be the value to choose AND it is the limiting reagent. Here is a site that will show you in detail how to solve for each reagent.
