1. Determine the Molecular Weight
* Hydrogen (H): 1.008 g/mol (atomic weight) * 2 atoms = 2.016 g/mol
* Oxygen (O): 15.999 g/mol (atomic weight) * 2 atoms = 31.998 g/mol
* Total Molecular Weight (H₂O₂): 2.016 + 31.998 = 34.014 g/mol
2. Calculate the Percentage of Hydrogen
* (Mass of Hydrogen / Total Molecular Weight) * 100%
* (2.016 g/mol / 34.014 g/mol) * 100%
* = 5.93%
Therefore, hydrogen makes up approximately 5.93% of hydrogen peroxide.
