I am giving 11 points and if you give right answer I will give like and brainlist​

Answer 1

Explanation:

The atomic weight of fluorine is 19 g per mole and the molecular weight of fluorine is 38g per mole . Thus, 76 gram fluorine contains

19

76

=4 gram atom .

They also contain

38

76

=2 moles of fluorine molecules.

Thus, the number of molecules present in 76 gram of fluorine

38

76

×6×10
