Question

What is the molecular weight of oxygen molecule in kg?

Answer 1

HLO MATE HERE IS UR ANSWER

❤. one atom of "O" = 1×16 = 16 grams

❤. 16/1000 = 0.016kg

❤. A molecule of O2 = 2× 16 = 32 grams

❤. 32 /1000 = 0.032 kgs

HOPE THIS WILL HELP U

Answer 2

Hey mate...

The mass of 1 mole of oxygen atoms is around 16 grams (15.9994 g to be precise). Now one mole refers to 6.022*10²³ atoms. So if you divide the 16 g by this number, you get 2.656 * 10^-23 grams as the value of mass of one oxygen atom.

HOPE IT HELPS YOU....
