If 852.04 g Al(NO3)3 reacted with the 741.93 g Na2CO3, which would be the limiting reagent?

c. Use the limiting reagent to determine how many grams of Al2(CO3)3 should precipitate out in the reaction.

d. If only 341.63 g of Al2(CO3)3 precipitate were actually collected from the reaction, what would the percent yield be?

Have I given you this page before. It will work all of your stoichiometry problems. For limiting reagent problems, just work the stoichiometry problem for each reactant, then the one producing the smaller number of mols of the product is the limiting reagent.
