Answer:
The enthalpy change for the solution process
= - 158.34 kJ/mol
Explanation:
Given that:
The mass of salt AX = 2.499 g
The mass of water = 135.3 g
The mass of the solution = ( 2.499 + 135.3 ) g = 137.799 g
The specific heat of salt solution s is known to be = 4.18 J/g° C
The change in temperature i.e. ΔT = 35.2 °C - 23.6 °C = 11.6 °C
Thus, the amount of heat raised is equal to the heat absorbed by the calorimeter.
∴





Recall that the mass of the salt = 2.499 g
The number of moles of the salt = 
= 0.0422 mol of AX
Finally the enthalpy change, 
= - 158.34 kJ/mol
The enthalpy change for the solution process
= - 158.34 kJ/mol
