HELP MEDAL WILL BE AWARDED A solution is made by dissolving 2.5 moles of sodium chloride (NaCl) in 198 grams of water. If the molal boiling point constant for water (Kb) is 0.51 °C/m, what would be the boiling point of this solution? Show all of the work needed to solve this problem.

Hi you have to calculate first the molality of the solution molality = moles of solute / kg of solvent then use the formula deltaT= Kb x molality of the solution boiling T of the solution = Kb x molality + boiling point of the water (100C)
