Determine the original mass of liquid g that was placed in, Ask an Expert

Academics

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 18g/mol. Its molar heat of vaporization is 44kJ/mol. Its normal boiling point is 373K. A scientist measures the pressure inside the container as a function of temperature and notes that for temperatures at or below 512K, the pressure increases exponentially with T^-1. However, for temperature about 512K, 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=512K
