Science Question of the Day

This one will take some chemistry knowledge. Pardon the fact there are no subscripts for the compounds. This is a problem from my Ch. 9 Stoichiometry test I gave about 3 weeks ago.

If 325g Lead(II) Sulfate racts with 190g Lithium metal, how many grams of each product will be formed?

1, you have to find out what the products will be (Single-replacement rxn)
2, write a balanced equation
3, find out which reactant will be the limiting reactant
4, use limiting reactant as the "given" or "known", proceed with stoichiometry
5, do the math
Repeat 4,5 for the other product as well.

Good luck.
