Many gases are shipped in high-pressure container. Consider a steel tank whose volume is 55.0 L and which contains O2 gas at a pressure of 16500 kPa at 25 degrees C. (a) What mass of O2 does the tank contain? (b) What volume would the gas occupy at STP? (c) At what temperature would the pressure in the tank equal 150.0 atm? (d) What would be the pressure of the gas, in kPa, if it were transferred to a container at 24 degrees C whose volume is 55.0 L?
