Concentrated hydrochloric acid has 37.5% of HCl in mass and density of 1.2 g/cm3. What volume (in mL) of concentrated hydrochloric acid should be used to prepare 7 L of a 0.8 mol/L HCl (aq) concentration solution?

First determine the molarity of the concentrated HCl.
That is 1000 mL x 1.2 g/mL x 0.375 x (1 mol/36.5) = ? mols/L = M
Then mL1 x M1 = mL2 x M2
7000 mL x 0.8 M = mL2 x approx 12 M
Note: That 12 M is an estimate.
