A large steel nitrogen cylinder has a mass of 6.50 kg empty When it is at 1960.0 PSI (gauge pressure) and a temperature of 20.0 o C it has a total mass of 23.6 kg. What will be the pressure when the cylinder has a total mass of 19.9 kg? (Assume the temperature is still 20.0 o C)

What will be the pressure when the cylinder has a total mass of 19.9 kg? (Assume the temperature is still 20.0 oC) What if the temperature is 82.0 oC and the mass is 19.9 kg? (at 20 oC: 1547 PSI absolute, 1533 PSI gauge, at 82 oC: 1875 PSI absolute, 1860 PSI gauge)
