Osmotic concentration - Wikipedia
Osmolarity equals molarity times the van't Hoff i factor. The osmotic pressure of a 1 mol/L NaCl solution will be twice that of a 1 mol/L solution of The video below explains the difference between molarity and osmolarity. Osmotic concentration, formerly known as osmolarity, is the measure of solute concentration, a one-to-one relationship between the molarity and the osmolarity of a solution. For example, sodium chloride (NaCl) dissociates into Na + and Cl− ions. Thus, for every 1 mole of NaCl in solution, there are 2 osmoles of solute. The molarity of a solution is the number of moles of solute per litre of solution. M= nV. You have to convert the mass of NaCl to moles of NaCl.
Подумайте. Это не лишено смысла. Джабба сразу понял, что Сьюзан права.
