Why is the molecular mass of polymers expressed as an average?
Why is the molecular mass of polymers expressed as an average?
Options
- APolymers have a uniform chain length.
- BThe molecular mass of polymers cannot be determined.
- CPolymers contain chains of varying lengths.
- DPolymers always have a specific molecular mass.
Correct answer
C. Polymers contain chains of varying lengths.
Step-by-step solution
The molecular mass of polymers is expressed as an average because polymer samples contain chains of varying lengths, and it is not a uniform value.
