Choroform , CHCl(3), boils at 61.7^(@)C....

Choroform , `CHCl_(3)`, boils at `61.7^(@)`C. If the `K_(b)` for choroform is `3.63^(@)C//"molal"`, what is the boiling point of a solution of 15.0 kg of` CH_(3)` and 0.616 kg of acenaphthalene, `C_(12)H_(10)` ?

A

`61.9^@C`

B

`62.0^@C`

C

`52.2^@C`

D

`62.67^@C`

Text Solution

Verified by Experts

The correct Answer is:

D

`DeltaT_b = K_b.m rArr 3.63 xx (0.616 //154)/(15) xx 1000`,
`T_b = 61.7 + 0.968`
`rArr 62.67^@C`
