Potency of HCl(l) is 35% (w/w) and density 1.19 g/cm3. Calculate the molarity of the Acid? [Molecular Weight of HCl is 36.5].

1 answer

mass of 1000 mL is 1.19 g/cc x 1000 cc = ??g,].
How much of that is HCl? ??g x 0.35 = xx g.
How many moles is that? xx g HCl/molar mass HCl.

moles/L is definition of molarity.
