92 g. of ethanol is dissolved in 108g. Of water. The mole fraction of water in the solution is

A

0.25

B

0.75

C

0.5

D

0.35

Text Solution

Verified by Experts

The correct Answer is:
A
`"Moles of ethanol"="Mass"/("Molar Mass")=92/46=2`
and moles of water `= 108/18=6`
mole fraction of ethanol `=2/(2+6)=0.25`
