Sodium bicarbonate, NaHCO3, is used in baking (baking soda), fire extinguishers, and in the manufacture of plastics and ceramics. It decomposes according to the equation shown below. What is the molar mass of Na2CO3? 2NaHCO3 → Na2CO3 H2O CO2 If your answer is less than 100.0 g/mol, eliminate the graduated cylinder. If your answer is greater than 100.0 g/mol, eliminate the beaker.
