ihave two solutions. in the first solution , 1.0 moles of sodium chloride is disslved to make 1.0 liters of solution . in the second one, 1.0 moles of sodium chlorine is added to 1.0 liters of water.is the molarity of each solution the same?
No they are not.
M = moles/L solution which is not the same as moles + 1000 mL H2O. The latter will be more than a liter of solution.
