Using Raoult's law for water and Henry's law for nitrogen, calculate the pressure and gas-phase composition (mole fractions) in a
system containing a liquid that is 0.500 mole% N2 and 99.50 mole% water in equilibrium with nitrogen gas and water vapor at 70.0 °C.
The Henry's law constant for nitrogen in water is recommended by NIST to be well represented by
KH = 0.000625 exp[1300 (1/T - 1/298.15)] mol N2/(kg H2O bar), where T is measured in Kelvin.

Please perform the tip capacity calculation two ways: For the first approach, assume that the total vertical stress at the pile tip is balanced by the weight of the pile. For the second approach, assume that the total vertical stress at the pile tip is not balanced by the weight of the pile (which means you need to include the vertical total stress term).
