Question

A 840 g quantity of ethanol, in the liquid state at its melting point of -114.4C, is frozen at atmospheric pressure. The heat of fusion of ethanol is 1.04x10^5J/kg and the molecular mass is 46.1 g/mol. The change in the entropy of the ethanol as it freezes, in SI units, is closest to: A 840 quantity of ethanol, in the liquid state at its melting point of -114.4, is frozen at atmospheric pressure.
