The Mole Concept, Unit 5 Assessment, Mole Conversions Week 20 Chemistry

Warm Up: 4 Minutes In everyday life we use counting units like the dozen (12 objects) and gross (144 objects) to deal with large quantities. In chemistry, the unit for dealing with atoms, ions, and molecules is the mole. Based on this, define the term mole in YOUR OWN WORDS. Sit anywhere you’d like Write the Learning Target No more than 4 people per row You DO NOT have to copy the question

How many particles? Timberlake, Chemistry 7 th Edition, page 179

What is a Mole???

1 Mole of a Substance 6.02 x particles (atoms, molecules or formula units) Avogadro’s Number

How Big is a Mole? One mole of marbles would cover the entire Earth (oceans included) for a depth of three miles. One mole of $100 bills stacked one on top of another would reach from the Sun to Pluto and back 7.5 million times. It would take light 9500 years to travel from the bottom to the top of a stack of 1 mole of $1 bills.

White Board Jeopardy Students will work in groups of 3 to 4 (Team number is on the desk in front of you). Students will need Dry Erase Board, Marker, Periodic Table, Nomenclature Sheet, and Eraser. NOTES are allowed during White Board Jeopardy

White Board Jeopardy How to Play??? 1. Write your team number in the upper right hand corner 2. During the song, you will work the problem shown in your lap INDIVIDUALLY. 3. At the end of the Jeopardy song, you will talk with your group. 4. When Mr. Ghosh says “Boards Up”, all students in group must have Identical responses on their Dry Erase Boards that are correct in order to receive FULL CREDIT. Boards that are not up will not be counted. 5. You may be called on randomly to explain your answer. If I do this and you cannot explain correctly, your team will NOT receive credit. Team #

Scoring and Rules/Expectations Scoring: 1. All questions are worth 1 point Rules/Expectations: 1. No talking during the Jeopardy song 2. Must be working individually during the song 3. No arguing with Mr. Ghosh about scoring 4. Must be explaining WHY during group work time Any violations of the rules/expectations will result in your team losing a point

Prizes! The team that finishes with the most number of points will receive 5% extra credit on the Exam tomorrow.
