Sodium hydroxide is dissolved in enough water to make up a 20.0 mole% solution. If the NaOH and water are initially at 77°F (25°C), how much heat (Btu/lb product solution) must be removed for the solution also to be at 77°F. Assume the process is carried out at constant pressure, so that Q = ΔH, and use Table B.11 to evaluate ΔHs.
