The formula for Aluminum Nitrate is Al(NO₃)₃.

To calculate the molar mass of Aluminum Nitrate, we need to determine the atomic masses of aluminum (Al), nitrogen (N), and oxygen (O) from the periodic table. The atomic mass of aluminum is approximately 26.98 grams per mole (g/mol), the atomic mass of nitrogen is approximately 14.01 g/mol, and the atomic mass of oxygen is approximately 16.00 g/mol.

In Aluminum Nitrate (Al(NO₃)₃), there is one aluminum atom (Al), one nitrogen atom (N), and three oxygen atoms (O). So, we can calculate the molar mass as follows:

Molar mass of Aluminum Nitrate (Al(NO₃)₃) = (1 × Atomic mass of Al) + (1 × Atomic mass of N) + (3 × Atomic mass of O)

Molar mass of Aluminum Nitrate = (1 × 26.98 g/mol) + (1 × 14.01 g/mol) + (3 × 16.00 g/mol)

Molar mass of Aluminum Nitrate ≈ 26.98 g/mol + 14.01 g/mol + 48.00 g/mol

Molar mass of Aluminum Nitrate ≈ 88.99 g/mol

Therefore, the molar mass of Aluminum Nitrate (Al(NO₃)₃) is approximately 88.99 grams per mole (g/mol).
