Answer 1

Hey mate

Here is your answer

Oxygen atomic number = 8

Mass of O2 = 8*2 = 16

Answer 2

ANSWER

The molecular weight of oxygen is 32 g/mol.

Hence, one mole of oxygen weighs 32 g.

One mole of oxygen contains 6.023×10^23

molecules.

The mass of one molecule of oxygen is:

6.023×10 ^23 ÷32

=5.31×10 ^-23g
