If you have an initial concentration and volume C1 and V1, and you dilute it with pure water (or whatever the solvent is) to a new total volume V2, the new concentration is C2 where
C1 * V1 = C2 * V2
(the added solvent is approximately (V2 - V1)
so V2 = C1 * V1/C2 = 100 uM * V1/ 50 pM
= 2x10^6 * V1
added solvent = V2 - V1 = 1,999,999 * V1
(very dilute!!!)
micro = 10^(-6), nano = 10^(-9), pico = 10^(-12), so a nM solution is strong than a pM solution.
