Calculate percentage of hydrogen in water
Given that the relative atomic masses in amu of H = 1, 0 = 16.

Explanation

To calculate the percentage of hydrogen in water (H₂O), we can follow these steps:

### Step 1: Determine the relative molecular mass of water (H₂O).
- Water consists of 2 hydrogen atoms and 1 oxygen atom.
- The relative atomic mass of hydrogen (H) is 1 amu.
- The relative atomic mass of oxygen (O) is 16 amu.

**Calculation:**
