An aqueous solution of urea containing 1...

An aqueous solution of urea containing 18 g urea in 2500 `cm^(3)` of the solution has a density equal to 1.052. if the molecular weight of urea is 60, the molality of the solution is

A

`0.200`

B

`0.192`

C

`0.100`

D

`1.200`

Text Solution

Verified by Experts

The correct Answer is:
B
1500 cc. solution `=1500xx1.052g =1578g`
Weight of solvent `=1560g`
Weight of solute =18 g
Molality `=("weight of solute")/("molecular weight of solute"xx)`
weight of solvent in kg
`=(18xx1000)/(60xx1560)=0.192` m
