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

A

0.1

B

0.19

C

0.086

D

0.05

Text Solution

Verified by Experts

The correct Answer is:
c
`"Mole fraction of" CH_(3)OH=(n_(B))/(n_(B)+n_(A))`
`=(5.2)/(5.2+1000/1B)=(5.2)/(5.2+55.5)=0.086`
