100%

A new enzyme has been just discovered that cleaves cell walls. A (1.8650x 10^-1) L sample of a solution of the enzyme that contains (7.6730x 10^-2)g of the enzyme exhibits an osmotic pressure of (1.41 x 10^-3) atm at 25 degrees C. Assuming ideal solution behavior, what is the molar mass of lysozyme?

Expert Solution

Step 1

The osmatic pressure is given by the formula,

$π = \frac{m}{M \times V} \times R T$

$π$ is the osmatic pressure

m is the mass of the enzyme

M is the molar mass of the enzyme

V is the volume of the solution

R is the gas constant

T is the temperature in Kelvin
