When 10 of a non-volatile solute ...

When 10 of a non-volatile solute is dissolved in 100 g of benzene . It raises boiling point by `1^(@)C ` then moles mass of the solute is ______.

A

223 g

B

233 g

C

243 g

D

253 g

Text Solution

Verified by Experts

The correct Answer is:
D
`Delta T_(b)=(K_(b)xx w xx1000)/(m xx W)`
`m=(K_(b)xx wxx 1000)/(Delta T_(b)xx W)=(2.53xx10xx1000)/(1xx100)=253 g`
