The pressure of a gas varies jointly with the amount of the gas (measured in moles) and the temperature and inversely with the volume of the gas. If the pressure is 960 kPa (kiloPascals) when the number of moles is 6 , the temperature is 320 Kelvin, and the volume is 720 cc, find the pressure when the number of moles is 4 , the temperature is 340K , and the volume is 480cc .
