If 6.00 g of CaCl2 • 2 H2O and 5.50 g of Na2CO3 are allowed to react in aqueous solution, what mass of CaCO3 will be produced? Answer the question by typing the answer in the space provided below the two calculations.
(6.00 g CaCl2•2 H2O/1)*(1 mole CaCl2•2 H2O/ g CaCl2•2 H2O)*( mole CaCO3/ mole CaCl2•2 H2O)*( g CaCO3/1 mole CaCO3) = g CaCO3
(5.50 g Na2CO3/1)*(1 mole Na2CO3/ g Na2CO3)*( mole CaCO3/ mole Na2CO3)*( g CaCO3/1 mole CaCO3) = g CaCO3
