(1) 41.592p How many moles of electron weigh ane kilogramx 10(3)6.023 109.108(1)6.023 109.108

Answer»

The mass of an electron is 9.1 * 10^-31 kg

Therefore number of electrons in 1kg = 1/(9.1 * 10^-31) electrons = 1.09 * 10^30 electron

Number of particles in 1 mole =6.023 * 10^23 (Avagadro’s constant)

So ,

Number of moles = number of electrons/ Avagadro’s constant = (1.09 * 10^30)/(6.023 * 10^23) = 1.8 * 10^6 electrons
