11.1 a Pure air consists of 78.03% by volume of nitrogen (molar mass 28.01), 29.05% by volume of oxygen (molar mass 32.00) and 0.98% by volume of argon (molar mass 39.95). Confirm that the molar mass of air is 28.97 and gas constant is 287.0 J kg-1K-1. (Take R - 8.314 kJ kmol-1K-1) b Find the molar mass of the products of stoi- chiometric combustion of a fuel representative of kerosene with the formula C H2n. Hence find the gas constant for the combustion products. (Ans: 28.91; 287.6 J kg-1K-1)
