Question

The balanced equation below shows the products that are formed when butane (C4H10) is combusted. 2C4H10 + 13O2 mc009-1.jpg 8CO2 + 10H2O

What is the mole ratio of butane to carbon dioxide?

1.)1:4
2.)1:5
3.)13:8
4.)13:10

Answer 1

The correct answer would be option 1. The mole ratio of butane to carbon dioxide is 1:4. Looking at the balanced chemical reaction, we see that we need 2 moles of butane to produce 8 moles of carbon dioxide. So, it is 2:8. Simplifying this by dividing both to 2, we have 1:4.

Answer 2

The mole ratio of butane to carbon dioxide is 1:4.

The correct option is 1) 1:4

What is the mole ratio?

The mole ratio tells about the ratio of moles of two elements in a chemical reaction.

Given,

$\bold{ 2C_4H_1_0 + 13O_2 = 8CO_2 + 10H_2O}$

In the reaction, there are 2 molecules of butane and 8 molecules of carbon dioxide.

2:8 = 1:4

Thus, the mole ratio of butane to carbon dioxide is 1:4 (1).
