CO(g) + O2(g) → CO2(g) Stoichiometry help

Question

CO(g) + O₂(g) → CO₂(g)

In the formation of carbon dioxide from carbon monoxide and oxygen, how many moles of carbon monoxide are needed to react completely with 3.44 moles of oxygen? (round to one decimal place)

Answer 1

Look at the mole ratio in the balanced equation

2CO + O2 ==> 2CO2

3.44 mol O2 x 2 mol CO/mol O2 = 6.88 moles CO
