0.378 g od an organic compound containing carbon and hydrogen was subjected to cobustion by Liebig's method , the CO_(2) and H_(2)Oformed were passed through potash bulbs and CaCl_(2) (anhydrous) tube. At end of the experiment, the increase in the respective weights were 0.264 g and 0.162 g. Calculate the percentage of carbon and hydrogen.
