Web11/17/2011 The Preparation of Calcium Carbonate Purpose: To create chalk (calcium carbonate) and to find the percentage yield in order to see the amounts of anhydrous sodium carbonate and calcium chloride were used up. Also to see if there’s any alterations like mass differentials. Objectives: 1. WebMolar mass of Calcium = 40.08 g/mol. That is to say, 1 mol of Calcium has a mass of 40.08 g. Also, according to Avogadro’s Number, 1 mole of Calcium has 6.022 x 10^23 atoms. Therefore, if you have 1.204 x 10²⁴ calcium atoms, this must have a mass of { (1.204 x 10²⁴)/ (6.022 x 10²³)} x 40.08 g = 80.13 g.
