a) A full propane cylinder from a camp stove leaks its contents of 0.464kg into a 3.66m4.27m2.44m room at 20C and 1atm. After some time, the fuel gas and room air are well mixed. Given that the lower limit of flammability min=0.51, the upper limit of flammability max=2.83, stoichiometric air fuel ratio A/Fsto=15.6 and the relative molecular mass of air is 28.85 . Determine whether the mixture in the room is flammable. [9 marks]
