Please correct answer and don't use hend raiting

The heat of vaporization of pure nitric oxide (NO) is 13.8 kJ/mol at its boiling point of -152 °C (when pressure is 1 atm).
If you add 0.154 moles of a fully soluble, non-dissociating substance to 1000 g of nitric oxide at -152 °C, how much will the temperature at which the
solution boils (at 1 atm pressure) increase? You may assume that AHvap of nitric oxide is constant over this temperature range. The molar mass of nitric
oxide is 30.01 g/mol.
increase in boiling T =
°C

9.96 Most first aid "cold packs" are based on the endothermic dissolution of ammonium nitrate in water: NH4NO3(s)NH4+(aq)+NO3(aq) H= 25.69 kJ A particular cold pack contains 50.0 g of NH4NO3 and 125.0 g of water. When the pack is squeezed, the NH4NO3dissolves in the water. If the pack and its contents are initially at 24.0°C, what is the lowest temperature that this bag could reach? (Assume that the ammonium nitrate solution has a specific heat of 4.25J g-l K-l, and that the heat capacity of the bag itself is small enough to be neglected.)
