To what volume would you need to dilute the above solution to make it 1.95 M?

Sagot :

Answer:

Using Dilution Factors

Example: Make 300 μL of a 1:250 dilution.

  1. Formula: Final Volume / Solute Volume = DF.
  2. Plug values in: (300 μL) / Solute Volume = 250.
  3. Rearrange: Solute Volume = 300 μL / 250 = 1.2 μL.
  4. Answer: Place 1.2 μL of the stock solution into 300 μL – 1.2 μL = 298.8 μL diluent.
