What is the mole fraction of the solute in 1 1.00 m aqueous solution-

A

0.177

B

0.177

C

0.0354

D

0.0177

Text Solution

Verified by Experts

The correct Answer is:
D
Molality `(m)=(1000xxn)/(NxxM),` Given, m=1
`therefore 1=(1000xxn)/(Nxx18) or, (n)/(N)=(18)/(1000) or, (n)/(n+N)=(18)/(1018)=0.0177`.
