Question

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?

Answer 1

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
