Potassium nitrate has a lattice energy of -163.8 kcal/mol and a heat of hydration of -155.5 kcal/mol.
How much potassium nitrate has to dissolve in water to absorb 105 kJ of heat? Express your answer using two significant figures.
Fisrt thing is that unit of energy is Kcal and KJ. So I have
calculated first heat of solution for mole in KCal and converted it
into KJ.
