A laboratory analysis of an unknown sample yields 73.13% carbon, 7.38% hydrogen, and 19.49% oxygen. What is the empirical formula of the sample? Give your answer in the form C#H#O# where the number following the element's symbol corresponds to the subscript in the formula. (Don't include a 1 subscript explicitly). For example, the formula CH,0 would be entered as CH2O. Type your answer and submit
