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.

im here

Answer 2

hey thx coulde you help me with this one..im not sure what the molalboing point constant is @shadowhuntergaming

Answer 3

sure hold on

Answer 4

ok @shadowhuntergaming

Answer 5

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)
