When a solid dissolves in water, heat may be evolved or absorbed. The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. Thermometer In the laboratory a general chemistry student finds that when 7.45 g of KBr(s) are dissolved in 108.50 g of water, the temperature of the solution drops from 23.02 to 20.00 C. Cardboard or Styrofoam tid The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.66 J/C. Nested Styrofoam cups Reaction occurs in solution Based on the student's observation, calculate the enthalpy of dissolution of KBr(s) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of water. AH dissolution = kJ/mol Submit Answer Retry Entire Group 8 more group attempts remaining When a solid dissolves in water, heat may be evolved or absorbed.
