How many moles of Carbon Dioxide produce when 0.136 moles of 1-penthanol react with excess oxygen?

Question

In a combustion reaction, by the way.

And, this is the formula:

2 C5H12O (l) + 15 O2 (g) → 10 CO2 (g) + 12 H2O (g)

Thanks in advance!

Answer 1

0.136 moles penthanol 10 moles of CO2
2 moles of penthanol
multiply 0.136 times 10 divided by two =0.68

Answer 2

(0.136 mols penthanol)[(10 mol CO2)/2 mol penthanol) ]= 0.680 mols CO2
