Ok so we have C = 98.28g, H = 16.21 g, and O = 65.2 g right

Good, now simply take the number of grams from carbon and divide it by the total amount which will give you a ratio of the amount of carbon in the compound

Then multiply by 100 for the percent :) make sense?

\[\frac{ Carbon }{ Total } \times 100\]
