9/6/2015· Use the mass of sodium carbonate to predict the mass of calcium carbonate that will form in your experiment. Note: if the monohydrate is used then the molar mass is not 105.98 g/mol but 124.00 g/mol because of the added mass of one mole of water per mole of sodium carbonate.
In chemistry, the molar mass is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. The molar mass is a bulk, not molecular, property of a substance. The molar mass is an average of many instances of the compound, which often vary in mass due to the presence of isotopes..
