Calculate the approximate temperature of a 0.40 mol sample of gas at 750 mm Hg and a volume of 11 L

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?
