What is the percentage of oxygen in sodium oxide?
The percentage of oxygen in sodium oxide is 72.7% as the chemical formula for sodium oxide is Na2O, which contains 2 oxygen atoms and 1 sodium atom. To calculate the percentage of oxygen, you divide the molar mass of oxygen by the molar mass of sodium oxide and multiply by 100.
