Sure! Let's calculate the molar mass of [tex]\( Al(OH)_3 \)[/tex] step-by-step.

### Step-by-Step Solution:

1. Identify the atomic masses from the periodic table:
- Aluminum (Al): 26.98 g/mol
- Oxygen (O): 16.00 g/mol
- Hydrogen (H): 1.008 g/mol

2. Count the number of each type of atom in [tex]\( Al(OH)_3 \)[/tex]:
- Number of Aluminum (Al) atoms: 1
- Number of Oxygen (O) atoms: 3
- Number of Hydrogen (H) atoms: 3

3. Calculate the molar mass of each component:
- For Aluminum (Al):
[tex]\[ 1 \times 26.98 \, \text{g/mol} = 26.98 \, \text{g/mol} \][/tex]
- For Oxygen (O):
[tex]\[ 3 \times 16.00 \, \text{g/mol} = 48.00 \, \text{g/mol} \][/tex]
- For Hydrogen (H):
[tex]\[ 3 \times 1.008 \, \text{g/mol} = 3.024 \, \text{g/mol} \][/tex]

4. Sum all the molar masses to find the total molar mass of [tex]\( Al(OH)_3 \)[/tex]:
[tex]\[ 26.98 \, \text{g/mol} + 48.00 \, \text{g/mol} + 3.024 \, \text{g/mol} = 78.004 \, \text{g/mol} \][/tex]

Therefore, the molar mass of [tex]\( Al(OH)_3 \)[/tex] is:

[tex]\[ \boxed{78.004 \, \text{g/mol}} \][/tex]
