if a student starts with 3.000 g of lead(II) carbonate for the first reaction and all other reagents are added in excess, what is the theoretical yield of lead(II) chloride solid?
lead is what is important here, so figure out how many moles of PbCO3 you have.
You will have that many moles of PbCl2
convert moles back to grams
