What is Molar Mass?

Molar mass is the mass of one mole of a substance. It is expressed in grams per mole (g/mol) and is calculated by summing the atomic masses of all the atoms in a molecule. For compounds like SiO2, the molar mass is determined by adding the atomic masses of silicon (Si) and oxygen (O).

Calculating the Molar Mass of SiO2

To calculate the Sio2 molar mass, we need to know the atomic masses of silicon and oxygen. The atomic mass of silicon is approximately 28.09 g/mol, and the atomic mass of oxygen is approximately 16.00 g/mol. Since SiO2 contains one silicon atom and two oxygen atoms, the calculation is as follows:

Molar mass of SiO2 = (1 × atomic mass of Si) + (2 × atomic mass of O)

Molar mass of SiO2 = (1 × 28.09 g/mol) + (2 × 16.00 g/mol)

Molar mass of SiO2 = 28.09 g/mol + 32.00 g/mol

Molar mass of SiO2 = 60.09 g/mol

Therefore, the Sio2 molar mass is 60.09 g/mol.
