A) Calculate the osmotic pressure of a solution containing 16.75 mg of hemoglobin in 15.7 mL of solution at 22 ∘C . The molar mass of hemoglobin is 6.5×104 g/mol. B) A 2.400×10−2M solution of NaCl in water is at 20.0∘C. The sample was created by dissolving a sample of NaCl in water and then bringing the volume up to 1.000 L. It was determined that the volume of water needed to do this was 999.4 mL . The density...
