A solution of sucrose (molar mass =342) ...

A solution of sucrose (molar mass =342) is prepared by dissolving 68.4 g in 1000 g of water. Calculate
The boiling point of solution.

A

`273`

B

`373.104`

C

`400`

D

`500`

Text Solution

Verified by Experts

The correct Answer is:
B
Boiling point of solution can be calculated by using the relation
`DeltaT_(b)=(K_(b) xx 1000 xx W_(B))/(W_(A) xx Mw_(B))`
Here `K_(b)=0.52 K m^(-1)`
`:. DeltaT_(b)=(0.52 xx 1000 xx 68.4)/(1000 xx 342)=0.104^(@)`
`:.` Boiling point of solution
= Boiling point of pure water + `DeltaT_(b)`
=`373 + 0.104 =373.104 K`
