How many molecules are found in a 0.36 mole sample of water? 2.17 x 10^28
4.49 x 10^23
2.17 x 10^23
7.12 x 10^23

idk what the question is about

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
