The solution with the highest concentration of solute particles will have the highest osmotic pressure.

Isosmotic solutions have the same concentration of solutes, while isotonic solutions have the same concentration of solutes and the same osmotic pressure.
Osmotic pressure is the pressure that develops when water moves across a semi-permeable membrane to achieve equilibrium in solute concentrations between two solutions. It is dependent on the concentration of solute particles in the solution and temperature.
Osmotic pressure depends only on the concentration of the solute particles in a solution, not the type of solute. Different substances at the same concentration will exert the same osmotic pressure because the number of solute particles per unit volume is what matters in determining osmotic pressure, not the identity of the particles.
The ability of a solution to do work by osmosis is determined by its osmotic pressure, which is the pressure needed to stop the flow of solvent into the solution through a semipermeable membrane. Solutions with higher osmotic pressure can exert more force and do more work through osmosis.
Osmotic pressure is the pressure exerted by water moving across a semipermeable membrane due to differences in solute concentration. Oncotic pressure, also known as colloid osmotic pressure, is the osmotic pressure exerted by proteins in the blood plasma that helps to maintain fluid balance between the blood vessels and tissues.
