Grams after: 3 Ca(NO3)2 +2Na3PO4 yields Ca3(PO4)2 + 6 NaNO3 reaction?

No idea how to start this one

How many grams of each material will remain in the reaction vessel after 15.0 grams of calcium nitrate reacts with 18.0 grams of sodium phosphate?

Now calculate the number of moles of each of the reactants and work out which one is the limiting reagent. This will tell you how much product you can make and how much starting material will be left over. :)
