Solution: Methylparaben is used in food and drugs and especially in beauty products although some studies have shown that it can disrupt endocrine production. A sample of methylparaben was decomposed to its elements – carbon, hydrogen and oxygen. The percentage of hydrogen was measured to be 5.26% and that a carbon was found to be 63.2%. An error was made in attempting to determine the percentage that was oxygen so this value was not reported. What is the empirical formula of methyparaben?   a. C8H8O3 b. C6H6O c. C2H6O d. CH2O e. CHO
