###### FREE Expert Solution

We are being asked to calculate the osmotic pressure of a 9.3×10−2 M potassium sulfate solution at 306K using the van’t Hoff factor in the table

Osmotic pressure (Π) is given by the equation:

where

i = van't Hoff factor

M = molarity

R = gas constant

T = temperature
