octane a compound found in gasoline has a density of 0.7020 g/ml. what is the mass (in g) of 2.252 L octane? Provide the answer with correct number of significant figures

d. temperate deciduous forest

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: )
