Mole fraction of a solution in 1.00 molal aqueous solution is

A

`0.1770`

B

`0.0177`

C

`0.0344`

D

`1.7700

Text Solution

Verified by Experts

The correct Answer is:
B
Mole fraction of solute
`="Moles of solute"/("Moles of solute" + "moles of solvent")`
`= 1/(1+55.56)[:. "Moles of solvent" = 1000/18=55.56]`
`1/56.56=0.0177`
