Question

2C4H10 + 13O2 ---> 8CO2 + 10H2O

What is the mole ratio of butane to carbon dioxide in the reaction shown above?
A. 1:4
B. 2:13
C. 4:5
D. 13:8

Answer 1

It is 1:4

Step-by-step explanation:

Let the mole ratio of Butane to CO2 be x.

8 moles of CO2 are produced by 2 moles of butane.

1 mole of CO2 will be produced by x

x = 2 / 8

x = 1 / 4

x = 1:4
