Energy of Phase Changes Practice Test

Liquid benzene at its melting point is converted to solid benzene at the same temperature. If $\Delta H_{fus}$ for benzene is $9.95\ \text{kJ/mol}$, how much energy is released when $0.80\ \text{mol}$ of benzene freezes?

A 27.0 g sample of ice at $0^\circ\text{C}$ melts completely at $0^\circ\text{C}$. The enthalpy of fusion of water is $\Delta H_{fus}=6.01\ \text{kJ/mol}$. How much energy is absorbed? (Molar mass of water $=18.0\ \text{g/mol}$.)
