Actually, since they give you volumes, you have no idea how many grams are in solution!
A 40% solution of NaCl would have a lot less mass of solute than a 40% solution of Fe2O3!
I keep getting 130gm for the answer!! Supposed to be 129.9 (I know it will round up, but rounded up is not the answer) I just need to know
A pharmacy has 325 mL of a 40% solution in stock. 120mL of sterile water is added to the solution to decrease the solution's concentration. How many grams of active ingredient would be in the diluted solution?
