The ratio of mass percent of C and H of an organic compound (C_(X) H_(Y) O_(Z)) is 6 : 1 . If one molecule of the above compound (C_(X) H_(Y) O_(Z)) contains half as much oxygen as required to burn one molecule of compound C_(X) H_(Y) completely to CO_(2) and H_(2)O . The empirical formula of compound C_(X) H_(Y) O_(Z) is -
