Question

calculate the weight of one molecule of O2 gas

Answer 1

16 is the answer.......................................

Answer 2

Answer:

5.31×10  ^−23  g.

Explanation:

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:

$\frac{32}{6.023 X 10^ -23} {}$

=5.31×10  ^−23  g.
