Question

The osmotic pressure of 0.1M HCl solution at 27° will be???
(1)2.16atmp
(2)0.164atmp
(3)4.92atmp
(4)0.008atmp​

Answer 1

Answer:

(3)4.92 atm

Explanation:

Given:

T=27 °C

=300 K

R=0.082

C=0.1 M

Solution:

We know that

π=iCRT

where

π=osmotic pressure of the gas

i=Van't hoff factor

C=concentration of the solution

R=universal gas constant

T=temperature

Van't hoff factor for HCl is 2 cause it dissociates into H⁺ and Cl⁻ in the solution.

Plugging in the values in the above formula

π=2*0.1*0.082*300

=4.92 atm

Hope this helps
