compressed gas tank was filled with either oxygen or helium but the lab technician cannot remember which gas they used. The tank's volume is 2 ft³ and its total filled-weight is 20.3 lbs. The tank itself weighs 20 lbs. A pressure gage attached to the tank reads 12 psi and the laboratory is kept at 80 °F. Determine if the gas in the tank is helium or oxygen. Show your calculations and provide a 1-2 sentence explanation to justify your conclusion.
