not much calculation there
.. 2 x 16 = 32 AMU per molecule
if you want that in grams
.. 32 AMU x (1.66x10^-24g / AMU) = 5.3x10^-23g
.. 2 x 16 = 32 AMU per molecule
if you want that in grams
.. 32 AMU x (1.66x10^-24g / AMU) = 5.3x10^-23g

Consider 1 mole of O2 molecules :
Mass of 1mole of O2 molecules = 16.0 × 2 = 32 g
Number of molecules in 1 mole of O2 = 6.02 × 10²³
Mass of one molecule of O2 = 32 / (6.02 × 10²³) = 5.32 × 10⁻²³ g
Mass of 1mole of O2 molecules = 16.0 × 2 = 32 g
Number of molecules in 1 mole of O2 = 6.02 × 10²³
Mass of one molecule of O2 = 32 / (6.02 × 10²³) = 5.32 × 10⁻²³ g
