Three capacitors having capacitances of 8.0 µF, 8.6 µF, and 4.1µF are connected in series across a 36-V potentialdifference.

(A) What is the charge on the 4.1μF capacitor? ( Express youranswer using two significant figures )

i tried to find it and my answers was : ( 7.5*10^2 ) , ( 745 ) , (17 ) , ( 74 ) , ( 74.2 ) all are wrong :(

(B) What is the total energy stored in all three capacitors?(Express your answer using two significant figures)

(C) The capacitors are disconnected from the potentialdifference without allowing them to discharge. They are thenreconnected in parallel with each other, with the positivelycharged plates connected together. What is the voltage across eachcapacitor in the parallel combination? (Express your answer usingtwo significant figures)

(D) What is the total energy now stored in the capacitors?(Express your answer using two significant figures)

Thanks alot !
