Pls help me answer the following questions and show the solution. I hope the answer is clear

B. Problem Solving (10 points) 6-10. What is the capacitance of a parallel plate capacitor with metal plates, each of area 1.50 m2, separated by 2.01 mm? What charge is stored in this capacitor if a voltage of 2.50 x 103 V is applied to it? 11-15. The capacitors have values C1 = 2.5 uF and C2 = 4.0 HF, C3 = 6.0 HF C4 = 8.0 uF and the potential difference across the battery is 12.0 V. Assume that the capacitors are connected in series. Find the equivalent capacitance of the circuit and solve for the potential difference across each capacitors
