Asolution is made by dissolving 9.74 g of sodium sulfate in water to a final volume of 165 ml of solution. what is the weight/weight % or percent by mass of the solute?

5.9

Explanation:

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!
