You're asking for the molar mass of sulfur dioxide (SO₂). Here's how to calculate it:

* Find the atomic masses:

* Sulfur (S): 32.06 g/mol

* Oxygen (O): 16.00 g/mol

* Multiply the atomic mass of each element by its subscript in the formula:

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

* Oxygen: 16.00 g/mol * 2 = 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 sulfur dioxide (SO₂) is 64.06 g/mol.
