If 2.33 L of propane (C3H8) at 24oC and 67.2 kPa is completely burned in excess oxygen, how many moles of carbon dioxide will be produced?

a. Write a balanced equation for the reaction.
b. Use stoichiometry to find the volume of carbon dioxide.
c. Use the ideal gas law to solve the number of moles of propane.

C3H8 + 5O2 ==> 3CO2 + 4H2O
Use PV = nRT and solve for n = number of mols C3H8

Using the coefficients in the balanced equation, convert mols C3H8 to mols of CO2.
I have no clue how to do b and c.
