Question
The solution containing 4.0 g of PVC in 1 L of dioxane was found to have osmotic pressure of 0.006 atm at 300 K. The molecular mass of the polymer PVC is
Options
A.16,420
B.1642
C.1,64,200
D.4105
Solution
$\pi = CRT \Rightarrow 0.006 = \frac{4}{M} \times 0.0821 \times 300 \Rightarrow M = 16420$
