Calculate the approximate Delta T(b) (in...

Calculate the approximate `Delta T_(b)` (in K ) for 0.001 molar KCI solution if its van's Hoff factors is 1.98.
[ `K_(b)` of water is `0.52 K kg mol^(-1)` ]

A

1.03

B

`1.03 xx 10^(-3)`

C

`1.03 xx 10^(-5)`

D

`1. 03 xx 10^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Delta T_b = I K_b m`
`= (1.98) (0.52) (0.001)`
`DeltaT_b = 1.029 xx 10^(-3) ~~ 1.03 xx 10^(-3)`
