How Do You Calculate Charge on Capacitors in a Circuit?

Homework Statement

Four capacitors are connected as shown in the figure below:

The Attempt at a Solution

(a) Find the equivalent capacitance between points a and b.
I found it to be 6.54μF.

(b) If ΔVab = 16.5 V calculate the charge on the the 24.0 μF capacitor.
108 μF (correct)

(c) If ΔVab = 16.5 V calculate the charge on the the 7.00 μF capacitor.
84.0 μF (correct)

(d) If ΔVab = 16.5 V calculate the charge on the the 2.00 μF capacitor.
I got 24.0 but its not correct.

(e) If ΔVab = 16.5 V calculate the charge on the the capacitor C, which equals 14.0 μF.
Likewise here.

Any help on parts d and e is appreciated.

You should start by checking your calculations for part(a); I get a slightly different answer than you. If you show me your work, I can show you where you went wrong.
