A cold pack manufacturer has decided to change the chemical in their cold pack from ammonium nitrate to ammonium chloride, a safer chemical. The original cold pack formulation used 100.0 g of room temperature (27.00C) water and 35.0 g of ammonium nitrate. Assume that the solution has the same density and specific heat capacity as water and that any heat lost to the calorimeter is negligible. The molar enthalpy of solution for ammonium nitrate is 25.7 kJ/mole and for ammonium chloride is 14.8 kJ/mole. a. b. Determine the lowest temperature reached using the original formulation
