Finding the Empirical Formula for Magnesium Oxide The Results In order to work out the ratio for magnesium and oxygen, I will have to calculate the amount of magnesium and oxygen used. From these results, and knowing that the Ar for Magnesium is 24, and the Ar for Oxygen is 16, I can find the number of moles for Magnesium and Oxygen. Investigation 1: Magnesium = 36.08 - 36.04 = 0.04g Oxygen = 36.11 - 36.08 = 0.03g Magnesium Ar = 24 Oxygen Ar = 16 Investigation 2: Magnesium = 36.10 - 36.03 = 0.07g Oxygen = 36.14 - 36.10 = 0.04g Magnesium Ar = 24 Oxygen Ar = 16 To ensure that my final answer was as accurate as possible, I did not round any numbers until the end to get the most accurate final equation. Likewise for test 1, 3, and the average. Investigation 3: Magnesium = 36.10 - 36.03 = 0.07g Oxygen = 36.19 - 36.12 = 0.07g Magnesium Ar = 24 Oxygen Ar = 16 To ensure...
