Read/review the following resources for this activity:
Textbook: Chapter 5, 6, 11
Unit 3 lesson
Initial Post Instructions
For your initial post pick a combination of one of the following molecules, one mass
quantity, and one total solution volume from this table. You may not use the same
combination as another student so be sure to read any existing peers postings before
posting your own.
Molecule Mass Volume
NaCl 2g 150 ml
CaBr2 6g 3L
Li3N 1g 500 ml
CaO 7g 14 L
For example, one possible combination would be 2 grams of NaCl in 500 ml of solution.
Then, give each of the following for your unique combination being sure to show all of
your work:
1. %mass/volume concentration
2. Molarity
3. Osmolarity
Make sure to post at least three high quality posts.
Follow-Up Post Instructions
Respond to at least two peers or one peer and the instructor. Further the dialogue by
providing more information and clarification.
Follow-up topics:
If a peer made a mistake in the initial post reply to your peer and walk us through
how to correct the mistake, showing all work.
Reply to one of peers initial posts and use the dilution equation to prepare a
more dilute solution. You may choose the final dilution that you are aiming for, just be
