Charges on capacitors in series are equal to each other and in this case also equal to the total charge. Therefore the charge on the third capacitor is equal to the total charge. If we know the charge, we can evaluate the voltage on the third capacitor. Voltages on both capacitors connected in parallel are the same.

So a capacitor charged to 8-volts placed in series with a 10-volt source will charge identically to a discharged capacitor (0-volts) placed in series with a 2-volt source. The difference between the two is that the first capacitor is, ultimately, charged to a higher voltage and when discharged each unit of charge will dissipate more energy.

After about $5 times RC$ the capacitor is charged to 99%. 9V. The capacitor''s rating has nothing to do with it, that only determines how high a voltage you can apply. Just look at what voltage is available, and that''s 9V. Just take care that the capacitor is fit for the supplied voltage. You can safely charge a 16V capacitor to 9V, but not ...
