Given the Osmotic pressure of Arginine vasopressin hormone its average molecular weight has to be calculated. Concept Introduction: In the process of osmosis , the solvent molecules pass through a semi - permeable membrane from less concentrated solution to more concentrated solution. The pressure that has to be applied to prevent the flow of solvent molecules is called osmotic pressure . It is expressed as, π = M R T Where, π = osmotic pressure M = Molar concentration R = Universal gas constant T = Temperature Molarity or molal concentration is a parameter that is used to express concentration of a solution . It is expressed as, Molarity = n u m b e r of m o l e s o f solute v o l u m e of solution in L

Question

Chapter 12, Problem 12.78QP

Interpretation Introduction

Interpretation:

Given the Osmotic pressure of Arginine vasopressin hormone its average molecular weight has to be calculated.

Concept Introduction:

In the process of osmosis, the solvent molecules pass through a semi - permeable membrane from less concentrated solution to more concentrated solution. The pressure that has to be applied to prevent the flow of solvent molecules is called osmotic pressure. It is expressed as,

π = MRT

Where,

π = osmotic pressureM = Molar concentrationR = Universal gas constantT = Temperature

Molarity or molal concentration is a parameter that is used to express concentration of a solution. It is expressed as,

Molarity = number of moles of solutevolume of solution in L
