An “instant cold pack” contains water and an inner pouch with 47.2 g of KNOZ. When the inner pouch is
broken and all of the KNO, is completely dissolved in water, the dissolving process absorbs 16.3 kJ of energy
(which "feels cold”). Calculate molar heat of solution (AHº) for this process in kJ/mol of KNO,.
