Hi,
1.Write out the balanced equation first
2.You could start by working out the moles for propane by doing mass/Mr (relative molecular mass)
3.Don't forget the molar ratio, scale your mol value up/down or it could remain the same.
4.Multiply the mole value by the Mr of Oxygen to find the final answer.

I hope this helps!
