A scuba tank, when fully submerged, displaces 15.7 liters of seawater. The tank has a total mass of 14 kg when empty; when full, it contains 3 kg of air. a) If you release the full (from from a spot underneath the surface of the ocean, does it sink, remain at that spot, or rise to the surface? Explain. b) If the tank is initially 2 m below the ocean surface, determine the pressure that the ocean water exerts on...

A mixture containing hydrogen and ammonia has a volume of 183.0 cm3 at 0.00 C and 1.0 atm. The mixture is cooled to the temperature of liquid nitrogen at which ammonia freezes out and the remaining gas is removed from the vessel. Upon warming the vessel to 0.00 C and 1 atm, the volume is 80.0 cm3. Using the ideal gas law, calculate the mole fraction of NH3 in the original mixture.
