Calculate the mass and charge of l mol of electrons

(i) Calculate the number of electrons which will together weigh one gram . (ii) Calculate the mass and charge on one mole of electrons .

The absolute charge on an electron is -

The charge of electron is ………

How much is the charge on an electron ?

In the Bohr model of a hydrogen atom, the centripetal force is furnished by the Coulomb attraction between the proton and the electrons. If a_(0) is the radius of the ground state orbit, m is the mass and e is the charge on the electron and e_(0) is the vacuum permittivity, the speed of the electron is

The specific charge of an electron is

If p is the resistivity of a material, and n is the number density of free electrons in it, the mean time between collisions between electrons in the material is given by: (m denotes the mass of an electron, and e denotes the charge on an electron)
