Which of the following law is used for calculating osmotic pressure?: (A) Bernoulli's law, (B) Ohm's law, (C) Van't Hoff law, (D) Poiseuille's law
Answer is C. Van't Hoff law is used for calculating osmotic pressure of a solution. Osmotic pressure of a solution depends upon the number of paicles in the solution. According to Van't Hoff law: Osmotic pressure: iC R = Gas constant T = Absolute temperature i = Number of ions C = Molar concentration Ref: Biophysics By P.S Mishra, page 108
