number of atoms in a molecule (you cant have half an atom!),so we have to figure out the whole number ratio by dividing by the smaller of the two numbers We still dont have whole numbers,though,so well need to multiply by some factor to get them to the closest whole number ratio.I see that if I multiply 1.5 by 2,I willusing the mole to calculate how many atoms are in a Each mole has the Avogadro constant number of molecules,So the number of molecules = 10 x 6.20 x10^23 molecules = 6.02 x 10^24.Finally each molecule contains 2 atoms of H and 1 atom of O.So there are 2 x 6.02 x 10^24 aroms of H and 6.02 x 10^24 atoms of O.Written in your way it would be for hydrogen atoms (180/18) * 6.02 x 10^24 = 2 atoms of H per molecule = 1.204 x 10^25 atoms H
