Text Solution

Verified by Experts

The correct Answer is:
A
(1) `0.74=(0.0821)/(250xx10^(-3))xx300((x)/(60)+(1-x)/(180))`
`x=0.176`
`%` urea `=(0.176)/(1)xx100=17.6`
(2) `(dP)/(P)=X_("solute")=((0.176)/(60)+(0.824)/(180))/(0.176/(60)+(0.824)/(180)+(250)/(18))=5.4xx10^(-4)`
(3) `DeltaT_(b)=mK_(b)=((40.176)/(60)+(0.824)/(180))xx(1000)/(250)xx0.5=0.015`
`DeltaT_(b)=100.015`.
