Question
**Analysis of Molar Mass Determination of an Enzyme**

The molar mass of an enzyme was determined by dissolving it in water, measuring the osmotic pressure at 20°C, and extrapolating the resulting fitting curve to zero concentration. The data obtained is presented in the following table:

| c/(mg cm⁻³) | h/cm  |
|-------------|-------|
| 3.221       | 5.746 |
| 4.618       | 8.238 |
| 5.112       | 9.119 |
| 6.722       | 11.990|

### Task
Calculate the molar mass of the enzyme. Refer to Atkins 3.38 (see hint in the textbook) for further guidance.

### Instructions
You are required to make a plot using the data in the table and apply all the available information to solve this problem. Any available software can be used to create this plot, such as graphing software or spreadsheet tools.

Ensure to extrapolate the fitting curve to zero concentration to determine the molar mass from the graph.
