Air contains 21% oxygen and 78% od nitrogen and 1% other gases.
How can you use this information to answer this question? What is your answer to this question?

1. Calculate density of CH4, H2 and CO at normal conditions (T = 20 C, p = 1 atm).
2. If mixture composes of 100 % CH4 it will have density you have calculated. If 100 % H2 - some other density. If 100 % CO - yet another density.
3. Calculate how many litres of air is needed to burn 1 litre of pure CH4, 1 litre of pure H2, and 1 litre of pure CO.
4. You know that mixture contains only CH4, H2 and CO.
5. Points 2, 3 and 4 gives you system of equations (3 equations with 3 variables) to solve.
That what my profesor said but i still dont know can you solve it, i really need this

The densities of H2, CO, and CH4 are 0.0899 g/l(STP) , 1.145 g/l(25℃, 1atm) and 0.657 g/l(25℃, 1 atm) respectively.

OK, but what with other steps
