A mass of G grams of a liquid are placed in a closed 15 liter, fixed-wall container. The molecular weight of the liquid is 18 g mol-1. Its molar heat of vaporization is 44 kJ mol-1. Its normal boiling point is 373 K. A scientist measures the pressure inside the container as a function of temperature and notes that for temperatures at or below 512 K, the pressure increases exponentially with T-1. However, for the temperatures above 512 K, the pressure is found to increase linearly with temperature. (Assume the heat of vaporization is independent of temperature.)

(a) determine the original mass of liquid, G, that was placed in the container. (Ignore the volume occupied by the liquid in these calculations)

(b) Determine the pressure that will exist inside the container when T= 512 K.
