Polymers, Materials & Chemical Design — Drills · Grade 11 Science
Chapter: Organic Chemistry & Material DesignWhat these drills covers
By the end of Polymers, Materials & Chemical Design you should be able to:
- I can connect monomers, repeat units, cross-links, and material behavior.
- I can compare material options using a stated function and life-cycle boundary.
2 questions, numeric and written answer, each with a worked explanation.
Vocabulary used: monomer, cross-link, thermoplastic.
Problem 1
Repeat-unit mass 44 g/mol and 200 units: estimated chain mass?
Hints
Write the relationship first; substitute with consistent units.
Answer and explanation
8800 g/mol
44×200=8800.
Problem 2
Does fragmenting into microplastic establish biodegradation?
Answer and explanation
No. The polymer can remain chemically present in smaller particles.
Response criteria
- State a scientifically accurate conclusion.
- Show the calculation or mechanism that supports it.
- Include units, conditions, or limits where relevant.
