The osmotic pressure of blood at normal body temp of 37 deg C is 7.65 atm. Sometimes it is necessary to add a saline (NaCl) solution by intravenous injection to a patient in the ER. 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 deg C? a. none of the answers is even close b. 4.4 c. 2.2 d. 8.8 e. 17.6 i get 0.30
