What is the molar mass of Al2(SO4)

The molar mass of Al2(SO4) is calculated by adding up the atomic masses of all the atoms in the compound.

Aluminum (Al) has an atomic mass of 26.98 g/mol.
Sulfur (S) has an atomic mass of 32.07 g/mol.
Oxygen (O) has an atomic mass of 16.00 g/mol.

There are two aluminum atoms, so we multiply the atomic mass of aluminum by 2: 26.98 g/mol × 2 = 53.96 g/mol.
There is one sulfur atom and four oxygen atoms in the sulfate ion, so we multiply the atomic mass of sulfur by 1 and the atomic mass of oxygen by 4: 32.07 g/mol × 1 = 32.07 g/mol, 16.00 g/mol × 4 = 64.00 g/mol.

To find the molar mass, we add up the individual atomic masses: 53.96 g/mol + 32.07 g/mol + 64.00 g/mol = 150.03 g/mol.

Therefore, the molar mass of Al2(SO4) is 150.03 g/mol.
