the calculation of expected grams of calcium carbonate (CaCO 3 ) formed in the reaction of 1.

the calculation of expected grams of calcium carbonate (CaCO3) formed in the reaction of 1.40 grams of sodium carbonate (Na2CO3) with excess calcium chloride and the calculation of % yield if the actual yield of calcium carbonate is 1.28 grams
Na2CO3 + CaCl2 → 2 Na+ + 2 Cl- + CaCO3
