Given circuit is redrawn and shown in figure.
We see that there are three capacitors are in series and this series combination is in parallel with a capacitor.
Capacitance of all capacitors are same.
 
Equivalent resistance of three capacitors which are connected in series is C/3 .
If the equivalent capacitance C/3 is parallel to a capacitor of capacitance C,
then effective capacitance is (C/3)+C = (4/3)C

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
