The image above represents the molecular weight of homopolymer.

To compute for molecular weight of homopolymer, two essential parameters are needed and these parameters are **Degree of Polymerization (x)** and **Sum of Masses of Repeat Unit (M _{o}).**

The formula for calculating the molecular weight of homopolymer:

M = xM_{o}

Where;

M = Molecular Weight of Homopolymer

x = Degree of Polymerization

Mo = Sum of Masses of Repeat Unit

Let’s solve an example;

Given that the degree of polymerization is 12 and the sum of masses of repeat unit is 24. Find the molecular weight of homopolymer?

This implies that;

x = Degree of Polymerization = 12

Mo = Sum of Masses of Repeat Unit = 24

M = xM_{o}

M = (12)(24)

M = 288

Therefore, the **molecular weight of the homopolymer** is **288**.

**Calculating the Degree of Polymerization when the Molecular Weight of Homopolymer and the Sum of Masses of Repeat Unit is Given.**

x = ^{M} / _{Mo}

Where;

x = Degree of Polymerization

M = Molecular Weight of Homopolymer

Mo = Sum of Masses of Repeat Unit

Let’s solve an example;

Given that the molecular weight of homopolymer is 140 and the sum of masses of repeat unit is 70. Find the degree of polymerization?

This implies that;

M = Molecular Weight of Homopolymer = 140

Mo = Sum of Masses of Repeat Unit = 70

x = ^{M} / _{Mo}

x = ^{140} / _{70}

x = 2

Therefore, the **degree of polymerization** is 2.

**Calculating the Sum of Masses of Repeat Unit when the Molecular Weight of Homopolymer and the Degree of Polymerization is Given.**

M_{o} = ^{M} / _{x}

Where;

Mo = Sum of Masses of Repeat Unit

M = Molecular Weight of Homopolymer

x = Degree of Polymerization

Let’s solve an example;

Given that the degree of polymerization is 14 and the molecular weight of homopolymer is 280. Find the sum of masses of repeat unit?

This implies that;

M = Molecular Weight of Homopolymer = 280

x = Degree of Polymerization = 14

M_{o} = ^{M} / _{x}

M_{o} = ^{280} / _{14}

M_{o} = 20

Therefore, the **sum of masses of repeat unit **is **20.**
