If the mass of an electron is `9 xx 10^(-28)` grams weight of one mole of electron is

The mass of one mole of electron is

The mass of one mole of electron is

If mass of an electron is 9.1xx10^(-31) kg, the number of electrons in 1 mg is

The rest mass of an electron is 9.11xx10^(-31) kg. Molar mass of the electron is

The kinetic energy of an electron is 4.55 xx 10^(-25) J .The mass of electron is 9.1 xx 10^(-34) kg Calculate velocity of the electron

Determine the de-Broglie wavelength of a proton, whose kinetic energy is equal to the rest mass energy of an electron. Given that the mass of an electron is 9.1 xx 10^(-31) kg and the mass of a proton is 1,837 times as that of the electron.

The kinetic energy of an electron is 4.55 xx 10^(-25) J .The mass of electron is 9.1 xx 10^(-34) kg . Calculate velocity of the electron.

The mass of an electron at rest is 9.1 xx10^(-31) kg. the mass of an electron, when it is moving with a speed of 2.4xx10^(8) m/s is (c=3xx10^(8) m//s)
