Given the balanced equation representing a reaction:

2CO(g) + O2(g)<==> 2CO2(g)

What is the mole ratio of CO(g) to CO2(g) in this reaction?

(1) 1:1 (3) 2:1

(2) 1:2 (4) 3:2

The answer is (1) 1:1. The mole ratio of reactants or productions of a reaction is equals to the ratio of coefficient before these compounds. The important thing is this formula must be balanced.
