Eh? Truth be told, I don't even get what I'm supposed to do. Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! The amount of acid in the new mixture is x + 100*0.35 = x+ 35.
The volume of the new mixture is x + 100.
Therefore the concentration of the new mixture is . That is letter c.
