You need to learn to do these yourself. You've posted several of the same kind of problem over the last few days and I've given you the step by step procedure here.

I can help if you tell me exactly what you don't understand. You already have moles. All you need to do is to convert for one substance to another and the way you do that is to use the coefficients in the balanced equation.
How many moles of CO2 would be made if you have 8 moles of C3H8?
C3H8 + 5O2 → 3CO2 +4 H2O
