Since the beginning of atomic age, it is a practice to store uranium as gaseous uranium hexafluoride (UF6, molar mass: 352 kg/kmol) in abandoned oil wells. The gas at the top of a 2 km deep well was sampled and found to be pure UF6 at 100 kPa, 300 K. Assuming equilibrium throughout the well, isothermal condition, and ideal gas behavior, determine the pressure (p) at the bottom of the well.
