Does NaCl Or CaCl2 Have A Higher Osmotic Pressure?

Does NaCl Or CaCl2 Have A Higher Osmotic Pressure? Does NaCl or CaCl2 have a higher osmotic pressure? NaCl dissociates into two ions, but calcium chloride (CaCl2) dissociates into three: one calcium ion and two chloride ions. Consequently, all else being equal, a solution of calcium chloride will have a higher osmolarity than a solution
