(5 pts) Suppose N2 and O2 have Henry's law constants of 9.8104 bar and 4.3104 bar in H2O, respectively. Calculate the ratio of the mole fraction of N2 to O2 in H2O, assuming the dry air above it is at atmospheric conditions. (4 pts) You have a closed container filled with an ideal gas at 3C and 2atm. If you set the reference point to be 3C and 1atm, what is the approximate enthalpy of the gas with respect to the reference? Briefly justify your answer. (4 pts) What is the reference state for the steam tables? Why is a reference state necessary? (5 pts) Suppose N2 and O2 have Henry's law constants of 9.8104 bar and 4.3104 bar in H2O, respectively.
