need formula to this. Carbon monoxide reacts with oxygen to produce carbon dioxide. If 3.0 Liters of carbon monoxide at STP, how many liters of oxygen are required to run the reaction
2CO + O2 ==> 2CO2
You can use the shortcut in this problem in which L is used directly as if L were mols.
3L CO x (1 mol O2/2 mol CO) = 3L x 1/2 - 1.5 L O2 needed.
