Johnny prepares a solution by mixing sodium acetate and water. To calculate the molarity of the solution, Johnny should calculate the moles of which substance, and why?

Sodium Acetate, because it is the solute.

Explanation:

In general water is typically the solvent, which would make sodium acetate the solute. Because molarity is moles of solute divided by liters of solution, Johnny needs to determine how many moles of sodium acetate he is adding to water to make the solution.

the dependant variable is spilled water

the independent is the heat

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: )
