Surfing For Agcl Is Precipitate?

Lizzie asks…How do you determine grams of a product from molarity of reactants?If 30.0 mL of .150M CaCl2 are added to 28.5 mL of 0.100M Ag(NO3), what is the mass of the AgCl precipitate?

I have the chemical equation worked out:
CaCl2 + 2 AgNO3 --> 2AgCl + Ca(NO3)2

Do I need to find the grams of both products and then try to determine which reactant is in excess? Any help is greatly appreciated!!Nancy answers:No, find mols and determine limiting reagent from ratio.

30.0ml X .150M CaCl2 =
