Solution:

Osmotic potential is a modern term for osmotic pressure. The osmotic pressure for a solution is positive, but its value is negative for osmotic potential.
Hence, Osmotic pressure = - Osmotic potential.
The osmotic pressure of 1M solution is 22.4 atm, hence for a 0.1M solution it will be - 2.24 atm.
