How Do You Calculate Equivalent Capacitance and Charge in a Complex Circuit?

[apatuka]

Homework Statement

Find the equivalent capacitance of the capacitor combination, Ct and the charge over C5:Q5
Vab=10V
C1=3uF
C2=11uF
C3=12uF
C4=6uF
C5=9uF

Homework Equations

1) 1/Ct=1/C1+1/C4 = 2uF
2) 1/Ct= 1/C2+1/C5 = 99/20uF

Parallel:
2+99/20+12=379/20uF

Ct=379/20 uF

Charge over Q5:C5

Im failing at this part:
Q5=C5=V

The Attempt at a Solution

Im failing at this part:
Q5=379/20*10^-6= 1.895^-4uC

Hi apatuka, welcome to PF.
In the given circuit, the charges on C2 and C5 are the same. The voltage across them is given. Find the charge. Then find Q5:C5
