Question

The boiling point of an aqueous solution of a non volatile solute is 100.15°C. What is the freezing
aqueous solution obtained by diluting the above solution with an equal volume of water ? the value
and K, for water are 0.512 and 1.86 K molality
(1)-0.544 °C (2) -0.512 °C (3) - 0.272 °C
(4) - 1.86 °C​

Answer 1

Explanation:

By boiling pt

0.15 = 0.512 x m

By freezing pt

fp = 1.86 x m

Solve to get fp
