Is the molar mass of SiO2 60 g/mol (I took the molar mass of Silicon-28, and added Oxygen's atmoic mass-16 and doubled it since it's diatomic). Thanks for checking my work.

To determine the molar mass of SiO2, you need to find the atomic masses of silicon and oxygen, and then calculate the total molar mass by adding them together.

The atomic mass of Silicon-28 is correct, it is indeed 28 g/mol.

However, the atomic mass of oxygen is 16 g/mol, and it is not diatomic in SiO2. SiO2 is a molecule that consists of one atom of silicon and two atoms of oxygen.

So, to calculate the molar mass of SiO2, you multiply the atomic mass of silicon by one, and the atomic mass of oxygen by two, and then sum them up.

(1 * atomic mass of silicon) + (2 * atomic mass of oxygen) = (1 * 28 g/mol) + (2 * 16 g/mol) = 28 g/mol + 32 g/mol = 60 g/mol

Therefore, the molar mass of SiO2 is indeed 60 g/mol. Your original calculation is correct!

60.084 if you add in the decimals from the periodic table. The atomic mass of Si is not exactly 28 and O is not exactly 16 because of isotopes. Also, oxygen in the elemental state can be referred to as being diatomic; however, I wouldn't use that term in SiO2 because the oxygen atoms are not attached to each other.
