Problem

Membrane osmometry is a technique used to find the molecular weight of polymers by determining the osmotic pressure of a solvent across a semipermeable membrane. What is the molecular weight of the water soluble polymer, polyacrylamide, with a concentration of 100 g/L that produces an osmotic pressure of 8 × 10−3 atm at 25C?

1. 30,900 g/mol

2. 305,000 g/mol

3. 2,600,000 g/mol

4. 25,600 g/mol
