Calcium Chloride CaCl2 has a molar mass of 110 grams per mole. 11.0 grams of CaCl2 dissolved in 500 mL of water would have which concentration? A) 0.022 molar b) 5500 molar c) 2 molar d) 5.0 molarConsider the reaction CaO + CO2 = CaCO3.. The molar masses are as follows: CaO = 56 grams per mole, CO2 = 44 grams per mole and CaCO3 = 100 grams per mole. If one begins with 2.8 grams of CaO and reacts it with excess CO2, how any grams of CaCO3 would be obtained? A) 6 grams b) 5.0 grams c) 4.4 grams d) 3.01 x 1022 grams.
