Finding the formula of magnesium oxide

Q. What is the percent composition of magnesium and MgO?

The percent composition of magnesium in magnesium oxide with a chemical formula of MgO is 60.30 percent.

Q. How do you calculate the percentage of magnesium in magnesium oxide?

The percentage of magnesium in the magnesium oxide from your experimental data % of Mg x 0.290 g MgO = 0.092g Mg % of Mg = 0.092 g Mg 0.285 g MgO x 100 = 32.3 % 4. Earth Topic: Determining the Empirical Formula of Magnesium Oxide 16 / 40 x 100% = ((40%)).

Q. What is the percent by mass of magnesium in MgO mm of MgO 40 g mol?

Similarly, this sample will contain 24.305 g of magnesium because magnesium has a molar mass of 24.305 g mol−1 . So in theory, you should have a 60.304% percent composition of magnesium in magnesium oxide.

Q. What is the percentage of O in MgO?

39.70 %

  1. Mass magnesium = 2.39 g.
  2. Mass magnesium oxide = 3.78 g.
  3. So mass oxygen = 1.39 g.
  4. Number moles Mg = 2.39/24 = 0.0995.
  5. Number moles O = 1.39/16 = 0.0868.
  6. Divide by the smallest to give the ratio aproximately 1 Mg : 1 O.
  7. This would suggest a formula of MgO, which is the correct formula.
