Four Capacitors: What is the charge on C4

[ajkess1994]

I have been struggling to figure this question out lately and could use some help setting it up correctly.

As shown in the figure, V = 9.0 V, C1 = C2 = 27.2 μF, and C3 = C4 = 13.6 μF. What is the charge on capacitor 4?

I have tried using the summation of charges and then multiplying by the given potential but I am not getting anywhere, can anyone help me?
