Gas is sampled at atmospheric pressure from the exhaust manifold of an internal combustion engine and analyzed. The mole fractions of the species in the exhaust are:

y(H2O) = 0.0468; y(CO2) = 0.0585; y(O2) = 0.123; y(N2) = 0.772

a) Assuming that the fuel is synthetic derived from coal with formula CHZ determine the atomic hydrogen to carbon ratio of the fuel (i.e. z).

b) Calculate the fuel-air equivalence ratio at which this engine is operating.

c) Is it possible to calculate the fuel's molecular weight with the given information? If so, what is the fuel's molecular weight? If not, what additional information would be required?
