electric-dipole moment is 4×10-8 cm ?????? I assume the unit is C-m (Coulomb-metre).
 
Torque begin mathsize 12px style equals bold space bold p with bold rightwards arrow on top bold space bold cross times bold E with bold rightwards arrow on top space equals space p cross times E cross times sin theta space equals space 4 cross times 10 to the power of negative 8 end exponent cross times 3 cross times 10 to the power of 4 cross times 1 half space equals space 6 cross times 10 to the power of negative 4 end exponent space N m end style

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?
