Asked by Narasaq

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.

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.
