Using a periodic table, you look up the atomic mass of all the atoms in the compound that you are dealing with, which in this case CaCO3. We have 50 g of CaCO 3, effectively we have half a CaCO 3. OR. Calculate the standard change in enthalpy, ÎH°rxn, for the decomposition of calcium carbonate to calcium oxide CaCO3 (s) â CaO (s) + CO2 (g) Given that: ÎH°f CaCO3 (s) = âŚ Compound: Moles: Weight, g: CaCO3*3Ca3(PO4)2: Elemental composition of CaCO3*3Ca3(PO4)2 ... Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. (A) 4 g of helium and 2 g of hydrogen contain the same number of molecules. Therefore, 1 mole of CaCO3 = 40.078 + 12.0107 + 15.9994 * 3 = 100.1832 moles/gram Thus, 50moles/100.1832moles per gram = 0.5 moles For finding the number of molecules, you times the amount of moles by Avogadro's number:: The Significance is that it contains only carbon atoms having molar mass of 12g only so that no. â
