Many gases are shipped in high-pressure containers. Consider a steel tank whose volume is 71.0 L and which contains O2 gas at a pressure of 17300 kPa at 25°C. (a) What mass of O2 does the tank contain? kg (b) What volume would the gas occupy at STP? L (c) At what temperature would the pressure in the tank equal 150. atm? K (d) What would be the pressure of the gas, in kPa, if it were transferred to a container at 24°C whose volume is 52.60 L? kPa
