The partial pressures of gas B dissolved in liquid A at 298 K are listed in the table below. If the vapor pressure of pure B at this temperature is 9500 Kpa, does this solution obey Raoult's Law? What is the Henry's Law constant for B? What is the partial pressure of B over a 0.25 molal solution of B dissolved in A if the molar mass of A is 74.1 g mol-1? XB 0.010 0.015 0.020 PB (in Kpa) 82.0 122.6 166.4
