Caproic acid, which is responsible for the foul odor of dirty socks, is composed of carbon, hydrogen, and oxygen atoms. a sample taken from a pair of abandon socks found in the locker room after a football game yielded 0.0930g of carbon, 0.0156g of hydrogen, and 0.0413g of oxygen. eww. they must have been worn more than once before being washed. find the empirical formula of caproic acid.
