Chapter 10, Problem 52QAP

Interpretation Introduction

Interpretation:

The molar mass of the enzyme needs to be determined, if the mass of enzyme is 7.89 g, volume of aqueous solution is 0.856 L and the osmotic pressure of the solution is 1.14 mm Hg at $22{}^{\circ }\text{C}$ .

Concept Introduction :

Osmotic pressure is a colligative property, and it its expression is as follows:

  $\Pi =MRT$

Where $\Pi$ is osmotic pressure of the solution in atm, M is the molarity of the solution in mol.L-1, T is the temperature in kelvin and R is the gas constant which has the value 0.0821 L.atm. mol-1.K-1.
