Simply total up the number of grams and calculate the percentage portion each one represents.

Divide the mass of each element by the combined mass of the compound, then, convert the decimal into a percent and divide each by it's own respective molar mass. After, divide each decimal by the smallest number out of the three, multipling by two if there are any .5's.
