Toxic Carbon monoxide gas is produced when fossil fuels such as gasoline, burn wihtout sufficient oxygen gas. The CO ca eventually be converted to CO2 inthe atmsphere. Automobie cata;yctic converters are desgned to speed up this conversion:

Question

How many moles of oxygen gas would be needed to convert 50.0 mol carbon monoxide to carbon dioxide?

What volume of oxygen gas would be needed to react with 986 L CO? (Assume both gases ar the same temp. and pressure)

Answer 1

2CO + O2 ==> 2CO2
50 moles CO gas will require 25 moles O2 gas.
986L CO x (1 mole O2/2 moles CO) = 986L x (1/2) = ?? L O2.
(NOTE: If reactants and products are in the form of gases and T and P are the same, one may treat volume (liters) as moles.
