In a test on some liquid fuels, decane is completely burnt in air.
2C10H22 + 31O2 → 20CO2 + 22H2O
What mass of oxygen would combine with 1 mol of decane?
A 15.5 g
B 248 g
C 496 g
D 672 g
Maybe I'm just being stupid but I can't work out how you'd get to an answer here please help me

Use the mole ratio of decane : oxygen to find the moles of oxygen that reacted
Then mass = moles x Mr of O2 and you should get your answer
