WebOct 10, 2024 · Molarity (M) of a solution is an expression of concentration, with one mole of solute per liter of solution. However, the molarity of a solution is not always the same as the solution’s osmolarity. This is because some solutes, such as ionic compounds like NaCl, dissociate into separate particles (e.g., Na + and Cl −) when dissolved in water. scoutbook handbook
