Which of the following units is useful in relating concentration of solution with its vapour pressure?

A

Mole fraction

B

Parts per million

C

Mass percentage

D

Molality

Text Solution

Verified by Experts

The correct Answer is:
A
According to Henary's law partial pressure of gas in the solution is proportional to the mole fractio of gas in the solution
`p=K(H)x`
where, `" "K_(H)`= Henry's constant
Hence (a) mole action is the correct choice.
