Yes, when you routinely test your product at the validated dilution, it must be within that acceptance criteria of 50-200% for your PPC. In order to determine which dilution you will be testing at the time of routine testing, you must perform validation testing including the inhibition/enhancement test phase prior to routine testing.

You can use the dilution equation, M1V1 = M2V2. In this problem, the initial molarity is 3.00 M, the initial volume is 2.50 mL or 2.50 x 10 –3 L and the final volume is 0.175 L. Use these known values to calculate the final molarity, M2: So, the final concentration in molarity of the solution is. 4.29 x 10–2 M.
