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 1.46 g of CaCl2(s) are dissolved in 107.70 g of water, the temperature of the solution increases from 25.53 to 27.94 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.59 J/°C. Based on the student's observation, calculate the enthalpy of dissolution of CaCl2(s) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of the water. ΔHdissolution =  ________ kJ/mol

Question
When 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 1.46 g of CaCl2(s) are dissolved in 107.70 g of water, the temperature of the solution increases from 25.53 to 27.94 °C.

The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.59 J/°C.

Based on the student's observation, calculate the enthalpy of dissolution of CaCl2(s) in kJ/mol.

Assume the specific heat of the solution is equal to the specific heat of the water.

ΔHdissolution =  ________ kJ/mol
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 1.46 g of CaCl,(s) are dissolved in 107.70 g of water, the Cardboard or Styrofoam lid temperature of the solution increases from 25.53 to 27.94 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be l1.59 J/°C. Nested Styrofoam cups Based on the student's observation, calculate the enthalpy of dissolution of CaCl2(s) in kJ/mol. Reaction occurs in solution. Assume the specific heat of the solution is equal to the specific heat of water. e t Cangage Lamng AHdissolution kJ/mol
