What is the mole fraction of the solute in a 1.00 m aqueous solution ?

A

0.0354

B

0.0177

C

0.177

D

1.77

Verified by Experts

The correct Answer is:

B

`m=(X_(A))/(X_(B))xx(1000)/(M_(B))`
`1=(X_(A))/((1-X_(A)))xx(1000)/(18)`
`1-X_(A)=55.5X_(A)`
`56.5X_(A)=1`
`X_(A)=(1)/(56.5)`
`thereforeX_(A)=0.0177`
