There are two kinds of hydrochloric acid, i.e.2mol/l hydrochloric acid and 6mol/l hydrochloric acid. If 200ml of 3mol/l hydrochloric acid is prepared, how many ml of 2mol/l hydrochloric acid and 6mol/l hydrochloric acid are required respectively There are two kinds of hydrochloric acid:2mol/l hydrochloric acid and 6mol/l hydrochloric acid. If 200ml of 3mol/l hydrochloric acid is prepared, how many ml of 2mol/l hydrochloric acid and 6mol/l hydrochloric acid are required

Let 2 mol/L hydrochloric acid be x,6 mol/L hydrochloric acid be y, then:(x+y=200.)(2x+6y=600), x=150y=50
