Chapter 6, Problem 6.83QP

Interpretation Introduction

Interpretation:

The osmolarity of $0.0005MKN{O}_3$ has to be determined.

Concept introduction:

The passage of solvent molecule occurs across the semi-permeable membrane due to the difference in osmotic pressure of solution and pure solvent.  Osmotic pressure is directly proportional to the concentration of the solute.  That is, whenever there is a concentration gradient setup between the semi-permeable membrane, the solvent will move from its higher concentration to the lower.

Osmolarity is the molarity of particles in solution and can be calculated as follow,

    Osmolarity $=i\times M$

Where, $i$ is the number of mol of particles/mol of solute and $M$ is the molar concentration of the solute.
