Is my answer true or false? To calculate the masses of CaCO3 and 20% HCl(aq) needed to get 50.00 grams of calcium chloride hexahydrate, we need to use stoichiometry. The balanced chemical equation for the reaction is: CaCO3 + 2HCl(aq) → CaCl2·6H2O + CO2(g) The molar mass of CaCl2·6H2O is 219.08 g/mo...
