Hi, Re TY, note: ALL info was put in terms of & each side of EQ has a total of 1 Liter of solution

how much  (0% acid) and how much stock solution (99%) of HCL

must he mix to get 1 liter 5% HCL solution

     Water = water

 

      .99x = .94L

         x = .94L/.99 =.95L of water needs to be added

CHECKING our Answer***

   .95L + .01*.05 = .95L

 from view of water

x+y=1

.01x+1.0y=.95(x+y)

x=0.0505051,   y=0.949495

from view of acid

x+y=1

.99x=.05(x+y)

x=0.0505051,   y=0.949495
