The molar mass of MgO is 40.3 g/mol (Mg: 24.3 g/mol, O: 16 g/mol). The molar mass contribution of oxygen in MgO is 16 g/mol. Therefore, the percent composition of oxygen in MgO is (16 g/mol / 40.3 g/mol) * 100 = 39.7%.

What is the percent composition of magnesium Mg in MgO?

The percent composition of magnesium (Mg) in MgO is 60%. This is because there is one magnesium atom (24.3 g/mol) and one oxygen atom (16.0 g/mol) in the formula unit MgO (40.3 g/mol), so dividing the molar mass of magnesium by the molar mass of MgO gives 0.603, or 60.3%.

Percent error of O in MgO?

To calculate the percent error of oxygen in magnesium oxide (MgO), you would compare the experimental value of oxygen in MgO to the theoretical value. The experimental value can be determined by chemical analysis, while the theoretical value can be calculated using the molecular formula of MgO. The percent error is calculated using the formula: (|Theoretical value - Experimental value| / Theoretical value) x 100%.

What is the percent by mass of oxygen in MgO?

The molar mass of MgO is 40.3 g/mol (24.3 g/mol for Mg and 16 g/mol for O). The mass of oxygen in MgO is 16 g, so the percent by mass of oxygen is (16 g / 40.3 g) x 100% ≈ 39.7%.
