If a `6.84%`(wt,vol.)solutionof cane sugar(mol.Wt.=`342`)is isotonic with `1.52%(wt.//vol.)`solution of thiocarbamide ,then the molecular weight of thiocarbamide is

A

`152`

B

`76`

C

`60`

D

`180`

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(1)=C_(2)`
`(w_(1))/(M_(1)xxV_(1))=(w_(2))/(M_(2)xxV_(2))rArr (6.84)/(342xx100)=(1.52)/(M_(2)xx100)M_(2)=76`
