Gas, as the particles have the most energy, and thus move the most.
Formula:

Given:
Density=3.4
Volume=500.0
Plug them into the formula:
Final answer: 1700g
If 0.5 L of solution contains 4 mol
then let 1 L of solution contain x mol
⇒ (0.5 L) x = (4 mol) (1 L)
x = (4 mol · L) ÷ (0.5 L)
x = 8 mol
Thus the molarity of the Sodium Chloride solution is 8 mol / L OR 8 mol/dm³.
