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

A

0.19

B

0.086

C

0.05

D

0.1

Text Solution

Verified by Experts

The correct Answer is:
B
5.2 molal solution means 5.2 moles of the solute `(CH_(3)OH)` are present in 1000 g of water, i.e., 1000/18 moles = 55.55 moles of water.
`therefore " Mole fraction of "CH_(3)OH`
`=(5.2)/(5.2+55.55)=0.086`
