You have analyzed an aqueous ammonia solution and find that it contains 30 wt% NH3.

(a) Use Figure 8.5-2 to determine the mass fraction of NH3 in the vapor that would be in equilibrium with this solution in a closed flask at 1 atm and the corresponding system temperature.

(b) If the Liquid phase in part (a) accounts for 90% of the total system mass, calculate the overall system composition and specific enthalpy using balances.
