What pressure will be exerted by 0.675 moles of a gas at 25*c if it is in a 0.750-l container?

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?
