Solution
At a given temperature, osmotic pressure of a concentrated solution of a substance is higher than that at a dilute solution..
Explanation:
`pi = CRT`
Where C is concentration of the solution. So, the higher the concentration of solution at given temperature the higher will be the osmotic pressure.
