Just having some trouble with this chemistry problem.. Thanks for help!

Toxic carbon monoxide (CO) gas is produced when fossil fuels such as petroleum burn without enough oxygen. The CO can eventually be converted to CO2 in the atmosphere. Automobile catalytic converters are designed to speed up this conversion:
Carbon monoxide gas + Oxygen gas → Carbon Dioxide Gas

a. Write the balanced equation for this conversion.

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

c. What volume of oxygen gas would be needed to convert with 968 L of carbon monoxide? (assume both gases are at the same temperature and pressure.)

1 answer

a. Write the balanced equation for this conversion.
2CO + O2 ==> 2CO2

b. How many moles of oxygen gas would be needed to convert 50.0 mol of carbon monoxide to carbon dioxide?
50.0 mol CO x (1 mol O2/2 mol CO) = ? mol CO2

c. What volume of oxygen gas would be needed to convert with 968 L of carbon monoxide? (assume both gases are at the same temperature and pressure.)
When dealing with gases one can use L directly without converting to mols.
968 L CO x (1 mol O2/2 mol CO) = ? L O2 needed.
