What is the molality m, of methanol in a solution prepared by dissolving `160 g` of methanol, `CH_(3)OH`, in `200.0 g` of water :

A

`1.0 m`

B

`5.0 m`

C

`10.0 m`

D

`25.0 m`

Text Solution

Verified by Experts

The correct Answer is:
D
Molarity `=("moles of solute")/("mass of solvent in kg")`
`=(160xx1000)/(32xx200)=25m`
