Question

The vapour pressure of an aqueous solution is found to be 750 torr at certain temperature t. If t is the temperature at which pure water boils

Answer 1

Answer:

P0 = 777 torr.

Explanation:

Here, I have presented the completion of your question along with options and answer.

The vapor pressure of an aqueous solution is found to be 750 torr at certain temperature T. If T is the temperature at which pure water boils under atmospheric pressure and same solution show elevation in boiling Tb = 1.04 K, find the atmosphericpoint  pressure (Kb = 0. 52 K kg mol–1 )  

(A) 777  

(B) 779  

(C) 782  

(D) 746

Solution:

(Dell) Tb = Kb m

P0 = 777 torr.
