    1.) 28.0 grams of oxygen

    28 grams (1 mole/16 grams per mole) = 1.75 moles oxygen

    2.) 5.0 moles of Iron

    5 moles (55.845 grams/1 mole) = 279.225 grams Iron

    3.) 452 grams Argon

    452 grams (1 mole/39.948 grams) = 11.315 moles Argon

    4.) 16.5 moles Hydrogen

    16.5 moles (1.01 grams/1 mole) = 16.665 grams Hydrogen
