What is Molar Mass?

Molar mass, often referred to as molecular weight, is the mass of one mole of a substance. It is expressed in grams per mole (g/mol). The molar mass of a compound is calculated by summing the atomic masses of all the atoms in its molecular formula. For SO2, the molecular formula consists of one sulfur (S) atom and two oxygen (O) atoms.

Calculating the So2 Molar Mass

To calculate the So2 Molar Mass, you need to know the atomic masses of sulfur and oxygen. The atomic mass of sulfur is approximately 32.07 g/mol, and the atomic mass of oxygen is approximately 16.00 g/mol. The calculation is as follows:

Molar mass of SO2 = (1 × atomic mass of S) + (2 × atomic mass of O)

Molar mass of SO2 = (1 × 32.07 g/mol) + (2 × 16.00 g/mol)

Molar mass of SO2 = 32.07 g/mol + 32.00 g/mol

Molar mass of SO2 = 64.07 g/mol

Therefore, the So2 Molar Mass is 64.07 g/mol.
