c) A CBU student is analysing fuel to see if it can be accepted by ZABS to be used on the market. The fuel has some impurities. An analysis of a canister of one mole of the fuel revealed the following constituents; 493208 1) The stoichiometric A/F ratio [6] Marks 2) with X% excess air (Where X= fifth and sixth digits of your student number). Find the A/F ratio [5] Marks 3) Find the Lambda ration () ? [2] Marks ight of Carbon atom =12, Weight of Hydrogen atom =1, Weight of Oxygen atom =16, ight of Nitrogen atom =14. You may assume that air contains 79% Nitrogen and 21% ygen, Assume the weight of 1 mole of unburnable Ash is 15% molar weight of C8H18
