hi could someone please explain to me how to go about doing question 16?

[Nathan]

firstly,write out the equation for the combustion of butane

2C₄H_10(g) + 13O_2(g) ----> 8CO_2(g) + 10H₂O_(l)

by molar volume principle, 2 l butane will give 13 l of oxygen

divide by two thus 1 l butane gives 6.5 l oxygen - answer C


btw, i don't have my answers, so let me know if that's right
