Question

Calculate the molal elevation constant of H2O, it being given that 0.1 molal aqueous solution of a substance boiled at 373.052K
​

Answer 1

Answer:

5.2 kelvin kilogram mole

Explanation:

change in boiling point=given temperature - 373 k

=373.052-373

=0.52

change in temp.=molal elvation×molarity

molarity of sol=0.1m

0.52= k×0.1

k=0.52/0.1

k=5.2
