Answer : The enthalpy change of dissolution of is -54.0 kJ/mole
Explanation :
where,
q = heat released by the solution
c = specific heat of water =
m = mass of solution = mass of water + mass of = 102.00 + 1.69 = 103.69 g
= change in temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy change of dissolution of
where,
= enthalpy change of dissolution = ?
q = heat released = 0.659 kJ
m = mass of = 1.69 g
Molar mass of = 138.55 g/mol
Therefore, the enthalpy change of dissolution of is -54.0 kJ/mole
