<prompt> Albumin exeing high oncotic pressure becauseHigh molecular weight and low concentrationLow molecular weight and high concentrationHigh molecular weight and high concentrationLow molecular weight and low concentration  <response>: Albumin 69000molecular weight is less compared to globulin90000-150000 and fibrinogen 340000.80of osmotic pressure of blood is exeed by albumin since it has highest concentration.
