06/03/2018· Solution: The desired solution requires (0.50 L) × (4.00 M L –1) = 2.0 mol of HCl. This quantity of HCl is contained in (2.0 mol) / (10.17 M L –1) = 0.197 L of the concentrated acid. So one would measure out 197 mL of the concentrated acid, and combine it with sufficient water to make the total volume of 500 mL.
