Chemistry 11 Mole Concept

C1 Explain the significance and use of the mole
Picture
This site has a video which describes the concept of the mole:
  • a mole is analogous to a dozen items; 
  • the amount of a substance (measured in grams) relates to the mole, and how you can "go back and forth between them" by using the molecular weight
  • when and why the concept of the mole is useful
The great thing about this video is that the website has provided the text along with the video; you could provide your students with a copy of this text for their notes.
If you assign this video to your students to watch at home then they can also answer the four multiple choice questions which follow the video.
