Charge on capacitors in a circuit?

[KingNothing]

The voltage from point a to point b is +28V.
Each capacitor has a capacitance of 4.00uF (microfarads)

What is the best way to calculate the charge on each capacitor?

Work like how you would for a resistor network. Find the equivalent capacitance then you can find the total charge. Then work your way back to the original circuit one step at a time, while finding the charge and voltage in each step. Its like working backwards from the equivalent capacitance to the original circuit. Remember the same rules that apply for series and parallel networks (in terms of voltage and current or charge in this case) will work here.
