What is the percent of Oxygen in H2O2?
The percent of oxygen in H2O2 (hydrogen peroxide) can be calculated by determining the molar mass of oxygen in the compound and comparing it to the molar mass of the entire compound.
The molar mass of oxygen is 16.00 g/mol. In H2O2, there are two oxygen atoms, so the total molar mass of oxygen in the compound is 2 * 16.00 = 32.00 g/mol.
The molar mass of H2O2 can be calculated as follows:
- Molar mass of hydrogen (H) = 1.01 g/mol
- Molar mass of oxygen (O) = 16.00 g/mol
- Molar mass of H2O2 = 2 * (1.01 g/mol) + 2 * (16.00 g/mol) = 34.02 g/mol
To calculate the percent of oxygen in H2O2, divide the molar mass of oxygen in the compound by the molar mass of the entire compound, and then multiply by 100:
- Percent of oxygen in H2O2 = (32.00 g/mol / 34.02 g/mol) * 100 = 94.12%
Therefore, the percent of oxygen in H2O2 is approximately 94.12%.
