What is the molar ratio between water and oxygen, given the following equation? 2C4H10 + 13O2 - > 8CO2 + 10H2O

A. 10:2

B. 10:13

C. 2:13

D. 8:10

B. 10:13

Explanation:

It is clear from the following balanced equation:

2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O

13 mole of oxygen (O₂) react with butane (C₄H₁₀) to give carbon dioxide (CO₂) and 10 moles of water (H₂O).

∴ The molar ratio between water and oxygen = (no. of moles of water : no. of moles of water) = (10:13)

So, the right choice is:

B. 10:13

10:13
