This Relative and Atomic Molecular Mass instructional video also includes:
Relative molecular masses sure have a lot of decimal places! Watch the video to learn how the number of particles in one mole of carbon-12 determines relative atomic and molecular masses. Viewers also learn how to calculate the atomic mass of an element as the average of the masses of its isotopes.

Instructional Ideas
- Use the video to introduce relative atomic and molecular masses
Classroom Considerations
- Learners must have knowledge of mole and Avogadro's number, which is covered in the Stoichiometry video
- Video uses terms that may be unfamiliar to viewers, such as quantum-mechanical interactions
- This video is hosted on YouTube
Pros
