Stoichiometry of Gases

Question

2. What volume of oxygen gas is needed to react completely with 0.626 L of carbon monoxide gas, CO, to form gaseous carbon dioxide? Assume all volume measurements are made at the same temperature and pressure

Answer 1

Hi Linsey,

 

2CO + O₂ ------->2CO₂

2 moles of carbon mono oxide reacts with 1 mole  of oxygen gas to form 2 moles of carbon dioxide

The volume  of O₂ = (1 mole O₂ / 2 moles CO)(volume of CO)

                           =0.5*0.626 L

                           =0.313 L
