## What is the molar mass of MgO 2?

56.3038 g/molMagnesium peroxide / Molar mass

## How do you find the molar mass of MgO?

The molar mass of magnesium oxide is (24.305 + 15.999) = 40.304 grams/mole.

**What is the mass of 2 molar mass?**

To find the molar mass of a compound you would use the periodic table to find the molar mass of each element separately. In our case, our two elements are iron and oxygen . Find the molar mass of Fe (55.85 g/mol) and O (16.00 g/mol).

### How do you find the mass of magnesium?

Example calculation:

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