Question

The molal elevation constant is the ratio of elevation in boiling point to ______.

Options

• mole fraction of solute

• molality of solution

• normality of solution

• molarity of solution

Answer 1

The molal elevation constant is the ratio of elevation in boiling point to molality of solution.

Explanation:

ΔT_b = K_b × m

`"K"_"b" = (Delta "T"_"b")/"m"`

K_b = molal elevation constant

ΔT_b = Increase in boiling point

m = molality of solution.
