`1M` of glucose solution has a freezing point of `-1.86^(@)C` . If `10 ml` of `1M` glucose is mixed with `30 ml` of `3M` glucose then the resultant solution will have a freezing point of

A

`-2.79^(@)C`

B

`-4.65^(@)C`

C

`-5.58^(@)C`

D

`-7.44^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
2
`DT_(f)=K_(f)xm`
`1.86=1.86xxmrArrm=1`
molality of `=(1xx1000)/((1000xxd-180))=1 rArr 1.18g//ml`
`M_(mix)=(10xx1+30xx3)/(40)=2.5M`
`DeltaT_(f)=-4.65^(@)C`
`T_(f)=-4.65^(@)C`
