Question: Question 12 ( 3 points) The enthalpy of solution for ammonium nitrate, NH4NO3, is +56.69 kJ/mol. Ammonium nitrate is commonly used in instant ice packs where it dissolves in water. How many grams of ammonium nitrate must be added to a 200.0 mL cold pack in order to cool the water (c=4.18 J/(g∘C)) from 22.0∘C to 2.00∘C ? Option: you may use the Chemistry

Question 12 ( 3 points) The enthalpy of solution for ammonium nitrate, ${\mathrm{NH}}_4{\mathrm{NO}}_3$, is $+56.69\mathrm{kJ}/\mathrm{mol}$. Ammonium nitrate is commonly used in instant ice packs where it dissolves in water. How many grams of ammonium nitrate must be added to a $200.0\mathrm{mL}$ cold pack in order to cool the water $\left(\mathrm{c}=4.18\mathrm{J}/\left(\mathrm{g}{}^{\circ }\mathrm{C}\right)\right)$ from $22.0^{\circ }\mathrm{C}$ to $2.00^{\circ }\mathrm{C}$ ?
