A welding fuel gas contains carbon and hydrogen only. Burning a small sample of it in oxygen  gives 3.38 g carbon dioxide, 0.690 g water and no other products. A volume of 10.0 L  (measured at STP) of this welding gas is found to weigh 11.6 g. Calculate (i) empirical  formula, (ii) molar mass of the gas, and (iii) molecular formula.
