1.	A welding fuel gas contain carbon and hydrogen only. burning a small sample of it in oxygen gives 3.38g carbon dioxide, 0.690 g of water and no other products .A volume of 10 litre ( measured at S T P ) of this welding gas is found to weigh 11.6 g. calculate (1) emperical formula (2) molar mass of gas, and (3) molecular formula.
