To solve this problem we have to use the rule of dilutions:

$V1\cdot C1=V2\cdot C2$

Where V1 is the initial volume, C1 is the initial concentration, V2 is the final volume and C2 is the final concentration.

Replace V1 for 0.560L, C1 for 43.6% and C2 for 20.4% and solve the equation for V2:

$\begin{gathered} V2=(V1\cdot C1)/(C2) \\ V2=(0.560L\cdot43.6\%)/(20.4\%) \\ V2=1.20L \end{gathered}$

It means that the final volume is 1.20L.
