Question

calculate the elevation in boiling point when 0.15 g of urea of molar mass 60 g of its dissolved in 75 g of water​

Answer 1

Answer:

Explanation:

Molality(m) = No. of moles of solute / Weight of solvent in kg

m= 0.0025/0.075 =0.33

Elevation in boiling point= Ebuloscopic constant(Kb)× molality = Kb × 0.33

Kb should be given in the question
