Which of the following concentration factors can be calculated if the mole fraction and density of an aqueous solution of `HCl` are known ?

Options

A. 1 only
B. 3 only
C. 1 and 2 only
D. 1, 2 and 3

Answer

D

Explanation

`Delta T = K_(f) xx (w_(B) xx 1000)/(m_(B) xx w_(A))`
`m_(B) = (K_(f))/(Delta T) xx (w_(B) xx 1000)/(w_(A))`
`= (6.8)/(2.8) xx (1.2 xx 1000)/(15) = 190`
