139916
One molecule of calcium carbonate, CaCO3, contains one atom of calcium, one of carbon and three of oxygen.
1072217
One molecule of carbon dioxide consists of 1 atom of carbon and 2 atoms of oxygen. We can calculate the mass of one molecule of carbon dioxide by adding together the masses of 1 atom of carbon and 2 atoms of oxygen.

Calcium's atomic mass is 40.08amu or 40.08 grams per mole. One mole of calcium contains 6.02 x 10 to the 23rd power(6.02e23) atoms. Take 0.6 grams and divide by 40.08 grams (0.0150) and multiply this factor by 6.02e23. That gives you 3.61e23 atoms.

A The empirical formula—Ca3(PO4)2—indicates that the simplest electrically neutral unit of calcium phosphate contains three Ca2+ ions and two PO43− ions. The formula mass of this molecular unit is calculated by adding together the atomic masses of three calcium atoms, two phosphorus atoms, and eight oxygen atoms.
