The mole fraction of the solute in one molal aqueous solution is:

A

0.009

B

0.018

C

0.027

D

0.036

Text Solution

Verified by Experts

The correct Answer is:
B
One molal solution means one mole of solute is present in 1 kg `(1000 g)/(18 g) = 1000/18`
Mole fraction of solute `=1/((1+1000/18)) = 18/1008 = 0.018`.
