Estimate the gas phase equilibrium mole fraction of the drug considered in Problem 2.17 at a temperature of 45°C. The pressure of the gas is 1 atm.

Problem 2.17

A new drug has a molecular weight of 325 and a melting temperature of 310°C. Estimate the solubility of this drug in hexane at 25°C. Use the Scatchard-Hildebrand equation to estimate the activity coefficient of the drug. Additional information needed to solve this problem is shown subsequently and in Example 2.10.
