Question: When Ca(OH) 2 is dissolved in water, it is known that the enthalpy of solution (DeltaH soln ) is -16.2 kJ/mol. Determine the change in

When Ca(OH)₂ is dissolved in water, it is known that the enthalpy of solution (\DeltaH_soln) is -16.2 kJ/mol.

Determine the change in temperature, in C, that would be measured in a coffee-cup calorimeter when 12 g of calcium hydroxide is added to 5000.0 mL of water.

Comment: The experiment is done at low concentration so you can neglect the mass of the reactant in the calculation of q_H2O.

Given: specific heat capacity of water = 4.186 J/gC; density of water = 1.00 g/mL; molar mass of calcium hydroxide = 74.093 g/mol

Enter the numerical value only, using 2 sig figs. Remember to include the sign for negative values.
