Calculate the percentage of oxygen in water (H₂O).
Explanation
To calculate the percentage of oxygen in water, we need to consider the molecular formula of water (H2O), which contains 2 hydrogen atoms and 1 oxygen atom. The atomic mass of oxygen is 16 g/mol, and the atomic mass of hydrogen is 1 g/mol. The molecular mass of water is 18 g/mol. The percentage of oxygen in water is (16/18) * 100 = 0.00005%.
