Carbon monoxide burns in oxygen to form carbon dioxide. what volume of oxygen at 25 degrees Celsius and 760. mmHg is required to react with 15.0 L of carbon monoxide which id at STP?

Answer 1

2CO + O2 ==> 2CO2
15.0 L CO at STP = 15.0/22.4 = ?mols
Convert mols CO to mol O2, then use PV = nRT at the conditions listed to solve for volume (in liters) of O2.
