Give typed explanation  An amount of calcium metal is contaminated by a certain amount of highly toxic, radioactive thorium metal (Th). A 20.00-gram sample of this mixture is dissolved in acid, and reacted with excess sodium oxalate to form a precipitate which is a mixture of calcium oxalate, CaC2O4, and thorium oxalate, Th(C2O4)2. The overall mass of the precipitate is 40.00 grams. What is the mass of each metal in the original 20.00-gram mixture? Mass of calcium? Mass of thorium?
