Calculate the osmotic pressure (in torr) of 6.00 l of an aqueous 0.958 m solution at 30.°c, if the solute concerned is totally ionized into three ions (e. g., it could be na2so4 or mgcl2).

The osmotic pressure is 54307.94 Torr.

Explanation:

To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

where,

= osmotic pressure of the solution = ?

i = Van't hoff factor = 3

C = concentration of solute = 0.958 M

R = Gas constant =

T = temperature of the solution =

Putting values in above equation, we get:

Hence, the osmotic pressure is 54307.94 Torr.
