mass of substances after all reactants are consumed
« on: April 21, 2010, 01:08:08 PM »
Hello all, I'm studying for an exam and this is one of the practice problems:

Aluminum nitrite and ammonium chloride react to form aluminum chloride, nitrogen, and water. What mass of each substance is present after 72.5g of aluminum nitrite and 58.6g of ammonium chloride react completely?

I have the balanced equation and I can convert to mols but I'm not exactly sure how to proceed. Am I supposed to treat this as a limiting reactant problem or percent yield or what?

Find out which reactant is the limiting reactant, then go ahead with your balanced reaction to find out moles of each of the products produced. Next, find out how many moles of Aluminum nitrite are left. Finally convert everything to mass
