Wait… I see it before… Why?

You have to derive the chemical equation for the combustion of butane (C4H10)

The chemical equation must be something like C4H10 + O2 → CO2 +H2O (without the coefficients)

I don’t know whether you know how to balance the equation, but after balancing the equation, it should be something like this:

C4H10 + 6.5 O2 → 4 CO2 + 5 H2O

Each mole of butane needs 6.5 moles of oxygen, so 13 moles of oxygen is required for 2 moles of butane in a complete combustion...

But for magnesium it required 1 mole...
