Problem
A rigid 10.0 L steel cylinder at 298 K contains 5.00 g of propane gas together with 10.0 L of pure oxygen gas (measured at 298 K and 1.00 atm) before ignition. The mixture is ignited, and the contents are allowed to return to 298 K after complete reaction. All liquid water formed condenses and remains in the cylinder.
(1) Write the balanced chemical equation for the combustion of propane in oxygen.
(2) Identify the limiting reactant and calculate the number of moles of carbon dioxide present after the reaction is complete and the system has returned to 298 K.
(3) Determine the total pressure, in atmospheres, of the gaseous contents in the cylinder at 298 K.
(4) Calculate both the mole fraction and the partial pressure of carbon dioxide in the final gaseous mixture.
