Saturated liquid carbon dioxide at a temperature of 293 k, Ask an Expert

Academics

Saturated liquid carbon dioxide at a temperature of 293 K and a pressure of 5.72 x 10⁶ Pa experiences throttling to a pressure of 1.01 x 10⁵ Pa. The temperature of the resulting mixture of solid and vapor is 195 K. What fraction is vaporized?

(The enthalpy of saturated liquid at the initial state is 24,200 J/mol, and the enthalpy of saturated solid at the final state is 6750 J/mo!. The heat of sublimation at the final state is 25,100 J/mol.)
