All dilution calculations are based on the mass conservation - final solution contains exactly the same amount of substance as the sample you started with (and vice versa).

I assume 1-1 is in fact l-1.

How much substance present in 50 mL of 0.1 μmol/l solution? In what volume of 0.2 mol/l solution is that amount of substance present?
