Ideal gas law/limiting reactant?

Ammonia and hydrogen chloride gases react to form solid ammonium chloride. A 10.0 L reaction flask contains ammonia at 0.463 atm and 22�C, and 129 mL of hydrogen chloride gas at 7.50 atm and 271 K is introduced. After the reaction occurs and the temperature returns to 22�C, what is the pressure inside the flask?
