Assume that you measured exactly 2.0 mL of the sodium chloride solution into a small test tube. How many moles of sodium chloride are in the tube?

e. as the distance increases by a factor, the electric force decreases by the square of that factor.

explanation:

as the distance increases by a factor, the electric force decreases by the square of that factor is the statement that best explains the relationship between the electric force between two charged objects and the distance between them.
