Mr. Avogadro has set up 4 jars with one mole of each the following substances: 1. Iron
2. Sodium Chloride
3. Sodium Bicarbonate (NaHCO3)
4. Aluminum
His clever and intelligent students notice that all of the amounts of the various
substances are different from one another, even though they are all ONE MOLE.
Explain the reason why each amount in the jar is different in terms of the mole. Then,
calculate the molar mass for each of the substances. Circle your your answers and
include the unit used for molar mass.
