Fool's gold is not gold at all but only lead IV sulfide. If you have 751.0 grams of lead how many grams of fool's gold can you make?
Given * (1/amu of given) * (mol of find/mol of given) * (amu of find/1mol)
Convert 751 g Pb to mols. mols = grams/atomic mass Pb.
Convert mols Pb to mols PbS2 using the coefficients in the balanced equation.
Now convert mols PbS2 to grams. g = mols x molar mass.
