5) a) A compound having molecular weight of 130 g/mol has the density of 1100 and 1024 kg/m' for solid and liquid phases respectively at its melting temperature of 425.15 K under 1 bar. When the pressure was increased to 125 bar the melting temperature increases to 427.45 K. Calculate AS° and AH° for the solid to liquid phase transition for this compound. b) Please explain why molality is prefered to use over molarity in colligative properties applications.
