Convert g to mols. mols = g/atomic mass
mols C = 97.30/12 = ?
mols H = 16.22/1 = ?
mols O = (200-16.22-97.3) = 86.48/16 = ?
Now find the ratio of each element to the others(in small whole numbers) with the smallest number being 1.00. The easy way to do that is to divide the smallest number by itself which makes sure that one is 1.00. Then divide all of the other numbers by the same small number.
