Hi, I have the following problem, for which im not sure if i should be making assumptions.(adsbygoogle = window.adsbygoogle || []).push({});

"a solid fuel assumed to consist of carbon and hydrogen only is burnt in air. an analysis of the dry products of combustion yields the following results: Oxygen, 02 = 5.45%

Carbon dioxide, CO2 = 10.71%

Nitrogen, N2 = 83.84%

I need to calculate gravimetric air fuel ratio, carbon & hydrogen content of fuel by mass.

Ive calculated the amount of air required to be 30.6kg for x kg of fuel, but the fuel is causing some problems?

Is the formula simply xCH2 + 0.21y02 + 0.79yN2??

Any help would be greatly appreciated.

Thanks
