How is osmolarity related to molarity?

Osmolarity is directly related to molarity through the van't Hoff factor. This factor accounts for the number of particles produced by a solute when it dissociates, influencing the osmotic pressure of the solution. Essentially, osmolarity equals molarity multiplied by the van't Hoff factor. Osmolarity and molarity are also related because they both measure the concentration of a solute in a solution, but they do so in slightly different ways. Molarity (M) measures the concentration of a solute in terms of the number of moles of solute per liter of solution. Osmolarity, on the other hand, measures the concentration of a solution in terms of the total number of solute particles (ions or molecules) per liter of solution. It takes into account the dissociation of solutes into ions if they are ionic compounds.
