This presentation offers good examples of calculating moles in chemistry. I found the examples very helpful when attempting to calculate the mole quiz myself. The links to the periodic table was very useful. I also like how if you did not calculate the answer properly it took you back the example to show you how to properly calculate the correct answer.
A suggestion to improve the StAIR is offer audio. I know for myself, especially in math, it helps me understand formulas if I hear it as I’m looking at the formula.
