A `5.2` molal aqueous of methyl alcohol, `CH_(3)OH`, is supplied. What is the molefraction of methyl alcohol in the solution ?

A

`0.190`

B

`0.086`

C

`0.050`

D

`0.100`

Text Solution

Verified by Experts

The correct Answer is:
B
Mole fraction of solute in aqueous solution
`= (m)/(m+(1000)/(18)) = (5.2)/(5.2 +(1000)/(18)) = 0.086`
