WebAnswer (1 of 5): What mass of concentrated hydrochloric acid (37% by mass, specific gravity 1.18) is needed to prepare 10% HCl solution by mass? If you have, say, 1 liter of a 20% solution, you would dilute it with an equal volume of water (to make a 2:1 dilution) to get two liters of a 10% solu... WebMolarity of 35% HCl is no mole of HCl/volume of solution => 0.97 mol/84.74 ml = 11.3 M The same is true for other percentages of HCl.
