13.9: Freezing Point Depression and Boiling Point Elevation
WebChemistry questions and answers. 13. _Which of the following aqueous solutions should have the lowest boiling point? a) 0.4 m MgBr2 b) 0.5 m Na2SO. c) 0.75 m NaCl d) 1 m … WebMar 10, 2024 · The freezing point of the solution will be 272.47 K. Explanation : Given data, W₂ = 10.5 g. W₁ = 200 g. Molar mass of MgBr, M₂ = 184 g. Kf of water = 1.86. Hence the change in freezing point is given by the relation, ΔTf = (1000 x Kf x W₂)/(W₁ x M₂) = (1000 x 1.86 x 10.5)/(200 x 184) Hence new freezing point , fraizer sports football helmets
