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.
