The molar mass of the given protein dissolved in 0.25 mL solution needs to be deduced given that the osmotic pressure at 25 C is 0.56 torr Concept Introduction: Osmosis refers to the net flow of solvent molecules across a semipermeable membrane from a region of higher concentration to a region of lower concentration Osmotic pressure (π) is the difference in pressure across a concentration gradient. It is directly proportional to the molarity (M) of a solution. π = iMRT -----(1) Where, R = gas constant and T = temperature i = Von’t Hoff factor which is the number of ions per mole of solute dissolved in a given solvent

Chapter 17, Problem 125AE

Interpretation Introduction

Interpretation:

The molar mass of the given protein dissolved in 0.25 mL solution needs to be deduced given that the osmotic pressure at 25 C is 0.56 torr

Concept Introduction:

Osmosis refers to the net flow of solvent molecules across a semipermeable membrane from a region of higher concentration to a region of lower concentration

Osmotic pressure (π) is the difference in pressure across a concentration gradient. It is directly proportional to the molarity (M) of a solution.
π = iMRT -----(1)

Where, R = gas constant and T = temperature

i = Von’t Hoff factor which is the number of ions per mole of solute dissolved in a given

solvent
