Discuss what is meant by a mole of something. How does Avogadro's number influence our understanding of the microscopic world? What are some ways you feel that Avogadro's number and the concept of a mole have personally affected your life?

Step 1
A mole is a counting unit used in chemistry to express amount of substance. One mole corresponds to exactly 6.02214076 × 10^23 elementary entities (such as atoms, molecules, ions, etc.). This number is known as Avogadro's number. It lets us move between the Show more…

After watching the videos, find one large-scale example of how big the quantity of a mole is. See above for an example, as well as the examples that are provided in the video: Avogadro's Number: 1 mole of anything is 6.02 x 10^23 of anything. In your post, include the following: 1. One large-scale example of how big the quantity of a mole is. You may not repeat any of the examples that are in the video, and you may not repeat any of your classmates' examples. 2. Explain why we do not use the quantity of the mole in everyday life (i.e., why is it not practical to have a mole of something that we can see?).

Give your own description of a mole. Identify a non-chemical example of how the mole concept can be used in determining the quantifiable relationship between two different things. Pick a random amount of any pure substance (for example: 5 grams ofwater) and determine how many moles there are. Show your calculations on as many examples as you need to become fluent in the idea that grams and moles are related.

The mole concept is related to everyday chemistry. For this exercise, you are going to calculate the number of molecules or atoms. Identify one food item, find out what elements or compounds are in this item. Explain how you would calculate the number of molecules or atoms of your interest. Respond others having a difficult time with calculation.
