A sample of gas has a volume of 80.0 mL and a temperature of 27 oC. If the gas is heated to 77 oC, calculate its final volume in mL. (P and n are constant)

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!
