Answer :
To determine the number of hydrogen atoms in the formula \(3 \text{Al(OH)}_3\), we can follow a step-by-step process:
1. Identify the number of hydrogen atoms in one unit of \(\text{Al(OH)}_3\):
- Each \(\text{OH}\) group contains 1 hydrogen atom.
- In \(\text{Al(OH)}_3\), there are 3 \(\text{OH}\) groups.
- Therefore, one unit of \(\text{Al(OH)}_3\) contains \(3 \times 1 = 3\) hydrogen atoms.
2. Determine the total number of units:
- The formula given is \(3 \text{Al(OH)}_3\), which indicates there are 3 units of \(\text{Al(OH)}_3\).
3. Calculate the total number of hydrogen atoms:
- Each unit of \(\text{Al(OH)}_3\) contains 3 hydrogen atoms.
- With 3 units of \(\text{Al(OH)}_3\), the total number of hydrogen atoms is \(3 \times 3 = 9\).
Thus, there are 9 hydrogen atoms in the formula [tex]\(3 \text{Al(OH)}_3\)[/tex].
