Question

The osmotic pressure of 0.013molar solution of an electrolyte is found to be 0.70atmosphere at 27°C. Calculate the Vant Hoff factor

Answer 1

Answer:

2.18

Explanation:

osmotic pressure(π) =iCRT

C is concentration term,R=0.0821,T is converted to Kelvin(273+27=300k)

i=π/CRT

=0.7

0.013×0.0821×300

=0.7

0.32019

i=2.18
