Strategy:
 For polymer solutions at low concentrations, osmotic pressure follows the relation . Identifying the y-intercept of the  vs  graph allows us to solve for .

Step 1: Extract data from the graph
The graph plots  (on the y-axis) against  (on the x-axis).
The intercept on the y-axis at  represents .
- Intercept value (from graph) .

Step 2: Solve for Molar Mass ()
