If 2.0 liters of oxygen gas react with excess carbon monoxide at STP, how many liters of carbon dioxide can be produced under the same conditions?


2CO (g) + O2 (g) yields 2CO2 (g)

b 2.0 L

c 4.0 L

s 6.0 L

Balanced equation
2CO (g) + O2 (g) yields 2CO2 (g)

Stoichiometry
1 moles of Oxygen produce 2 moles of Carbon dioxide

Number of moles is proportional to Volume [same temperature and same pressure]

Then 2 liters of Oxygen produce 4 liters of carbon dioxide.

Answer C: 4.0 L
