Here's how to calculate the molar mass of SO₂ (sulfur dioxide):

* Find the atomic masses:

* Sulfur (S): 32.06 g/mol

* Oxygen (O): 16.00 g/mol

* Multiply the atomic masses by the number of atoms in the molecule:

* Sulfur: 1 atom * 32.06 g/mol = 32.06 g/mol

* Oxygen: 2 atoms * 16.00 g/mol = 32.00 g/mol

* Add the results together:

* 32.06 g/mol + 32.00 g/mol = 64.06 g/mol

Therefore, the molar mass of SO₂ is 64.06 g/mol.
