Mar 06, 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.

    Oct 22, 2017 · solution concentration? Answer First, we must convert the 200 mL to liters: Since 1000 mL = 1 L We can write that, 200 mL x 1L/1000 mL = .20 L Therefore, Molarity = mol/L = .3 mol glucose/.20L = 1.5 mol/L = 1.5 M glucose. Now, if we modify the above example by changing the moles of glucose to grams of glucose, we will get the following question:
