The mixing of acetone and isopropanol is non-ideal, and thus must be quantified by an
activity coefficient. Given the data points in the table, what is the value of the activity coefficient for
acetone in the liquid phase when pressure is equal to 71.177 kPa? (You should assume the vapor
phase is an ideal gas).
