Question

Skin is prone to frostbite at temperatures starting at -0.55°C. Coldpack producers need to use caution when

preparing their coldpacks with potassium nitrate so as to not let their icepack get so cold it will lead to

frostbite. A coldpack producer has created a new coldpack recipe that consists of 75.00 grams dissolved in

250.0 grams of water. If this cold pack is activated at 18.00°C, will this coldpack be a frostbite risk? Clearly

show all work for calculations to support your answer. The literature ∆Hdissolution for KNO3 is 34.89 kJ/mol.

You can assume the solution has the same specific
