A. 165 lbs = ?? g
b. 12.01 cm = ?? m

a) 74842.7 g

b) 0.1201 m

Explanation:

1 pound is 453.592 g  

165 pound = 74842.7 g

12.01 / 100 = 0.1201 m

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!
