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. In the laboratory a general chemistry student finds that when 10.45 g of CsBr(s) are dissolved in 116.00 g of water, the temperature of the solution drops from 23.93 to 20.94 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.81 3/°C. Based on the student's observation, calculate the enthalpy of dissolution of CsBr(s) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of water. AHdissolution= kJ/mol #buton Thermometer Cardboard or Styrofoam lid Nested Styrofoam cups Reaction occurs in solution.
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. In the laboratory a general chemistry student finds that when 11.08 g of CsCl(s) are dissolved in 112.00 g of water, the temperature of the solution drops from 23.53 to 20.68 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.70 J/°C. Based on the student's observation, calculate the enthalpy of dissolution of CsCl(s) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of water.
