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

According to Henry’s law partial pressure of gas in the solution is proportional to the mole fraction of gas in the solution.
`p =K_(H)x`
where `K_(H)=` Henery's constant
Hence, (a) mole fraction is correct choice.
