Question

A 0.029 M solution of this ionic compound has an osmotic pressure of 1.50 atm at 25 C has van’s hoff factor that is equal to 3. The van’s hoff factor should be express in whole number

Answer 1

Using formula,

Osmotic pressure(P) = 1.50 atm

Temperature (T) = 298 K

Concentration(C) = 0.029 M

i = Van't Hoff factor

As we know,

$P = iCRT$

1.50 = i × 0.029 × 0.0821×298

i = 2.1

So, Van't Hoff factor is =[ 2]
