If any electric field exists in the conductor ,it would produce ordered motion of electrons without expense of external energy.This violates law of conservation of energy.PLEASE EXPLAIN THESE LINES

Explanation given in the book for Eelectric field E = 0 inside the conductor is not correct.
 
When a conductor is placed in electric field  Eo as shown in figure , free electrons or negative charges are driven to right side surface
leaving +ve charges on the left side surface .
This charge separation produces electric field Ein in opposite direction of Eo and both th fields cancel each other.
Hence resultant electric field is zero in the conductor

CBSE 12-science - Physics
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?
