PB(NO3)2(aq) + Na2SO4*10H2O(aq) Rightwards Arrow PbSO4(s) + 2NaNO3(aq)+10H2)(I)

water was added to a 2.4570 g sample, PbSO4 filtered and had mass of 0.8029g. Through trial Pb2+ was found to be the limiting reagent (not SO4,2+)

Determine the percent by mass composition of the original sample. How do I do this??? Thanks!
