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

A

0.086

B

`0.050`

C

`0.100`

D

`0.190`

Text Solution

Verified by Experts

The correct Answer is:
A
Moles of `CH_(3)OH, n_(CH_(3)OH)=5.2`
Moles of water, `n_("water")=(1000)/(18)=55.55`
`x_(CH_(3)OH)=(5.2)/(5.2+55.55)=0.086`
