The osmotic pressure of blood at normal body temperature of 37°C is 7.65 atm. Sometimes it is necessary to add a saline (NaCl) solution by intravenous injection to a patient in the emergency room. What should be the concentration of the NaCl solution (in g/L) so that it will have the same osmotic pressure as the blood at 37°C?
