The density of O_(2) at NTP is 1.429 g/L. Calculate standard molar volume of the gas.

A welding fuel gas contains carbon and hydrogen only. Burning a small sample of î in oxygen gives 3.38 g carbon dioxide, 0.690 g of 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.
