A mixture of propane and air with an equivalence ratio 0.9 (i.e. a weak mixture) is contained in a rigid vessel with a volume of \(0.5 \mathrm{~m}^{3}\) at a pressure of 1 bar and \(300 \mathrm{~K}\). It is ignited and after combustion the products are at a temperature of \(2600 \mathrm{~K}\) and a pressure of 9.06 bar. Calculate

(a) the amount of substance in the reactants;

(b) the amount of substance in the products and

(c) the amount of substance in the products per unit amount of substance supplied in the fuel. [0.02005; 0.02096; 0.0932;0.1368;0.01138;0.00261;0.02792; 0.7281]
