To go from moles to molecules we will apply Avogadro's law. Avogadro's law tells us that one mole of any substance contains 6.022x10^23 molecules. So applying this relationship, the calcium chlorate molecules will be:
[tex]MoleculesCa(ClO_3)_2=givenmolCa(ClO_3)_2\times\frac{6.022\times10^{23}molecules}{1molCa(ClO_3)_2}[/tex][tex]MoleculesCa(ClO_3)_2=2.3molCa(ClO_3)_2\times\frac{6.022\times10^{23}molecules}{1molCa(ClO_3)_2}[/tex][tex]MoleculesCa(ClO_3)_2=1.4\times10^{24}molecules[/tex]In 2.3 moles of calcium chlorate, there are 1.4x10^24 molecules
