Lab Assistance – Oxide of Magnesium

Magnesium Oxide

Background Theory

• Hmmm… how is it possible to determine a formula using simply mass measurements?
• Is there some sort of balanced reaction that SHOULD work?

Data

• Mass of crucible and cover
• Mass of crucible, cover, coiled magnesium
• Mass of crucible, cover, oxide (after reaction)

Calculations

• Mass Magnesium
• Mass reacted oxygen
• Moles Magnesium
• Moles Oxygen
• Mole Ratio (Mg/O)
• Percent Error

Analysis

• By what logic was your answer obtained?
• What factors introduced uncertainty? How did they impact your result?

Conclusion

• A statement about the direct result of your experiment (nothing else)
