Formula-Memory Connection: Strengthening Knowledge with Polymers Important Questions

Equations are more than just symbols –They're your secret code to solve problems in Chemistry. When you understand formulas, you can easily handle tricky ideas and feel more sure of yourself.  Use the equation with JEE Main Chemistry Polymers Important Questions JEE Main to improve studying. Check out our JEE Main Chemistry formula pages and begin your journey to prepare for JEE Main now!

Important Equations of Polymers

1. Degree of Polymerization (DP):

$DP = \frac{\text{Molecular mass of the polymer}}{\text{Molecular mass of the repeating unit}}$

2. Number-average Molecular Weight (\( \overline{M}_n \)):

$\overline{M}_n = \frac{\sum (n_i \cdot M_i)}{\sum n_i}$

Where $n_{i}$ is the number of polymer molecules with molecular weight $M_{i}$

3. Weight-average Molecular Weight (\( \overline{M}_w \)):

$\overline{M}_w = \frac{\sum (w_i \cdot M_i)}{\sum w_i}$

Where $w_{i}$ is the weight fraction of polymer molecules with molecular weight $M_{i}$   

4. Polydispersity Index (PDI):   

$\text{PDI} = \frac{\overline{M}_w}{\overline{M}_n}$

A higher PDI indicates a broader distribution of molecular weights.

5. Van der Waals Equation of State for Polymers:

$P = \frac{nRT}{V - nb} - \frac{n^2a}{V^2}$

Where P is pressure, V is volume, n is the number of moles, R is the gas constant, T is temperature, a is the van der Waals constant, and b is the excluded volume.
