Chapter 11, Problem 11.97SP

Interpretation Introduction

Interpretation:

The osmotic pressure ($\text{in mm Hg}$) would be expected for an aqueous solution of $\text{11}\text{.5 mg}$ of insulin in $6.60\text{ mL}$ of solution at $\text{298 K}$ has to be calculated.

The height of the water column in meters has to be calculated.

Concept introduction:

Osmotic pressure

The additional pressure that has to be given to solution in order to stop osmosis is called as osmotic pressure. Osmosis is the run of solvent into a solution by means of semipermeable membrane.

Osmotic pressure can be calculated by the equation,

$\text{π}\text{=}\text{MRT}$

$\begin{array}{l}\text{π=Osmotic}\text{pressure}\\ \text{M=}\text{Molarity}\text{of}\text{solution}\\ \text{R=Gas}\text{law}\text{constant}\\ \text{T=Temperature}\end{array}$
