Mass of an electron -9-1-xD7-10-x2212-28g1 mole -6-02-xD7-1023 electrons-x2234- molar mass of electron -9-1-xD7-10-x2212-28-xD7-6-02-xD7-1023-5-48-xD7-10-x2212-4 g-mole

The molar mass of an electron is:
$9.108 \times 10^{- 28}$ kg/mol
$6.023 \times 10^{23}$ g/mol
$5.486 \times 10^{- 4}$ g/mol
$9.108 \times 10^{- 24}$ g/mol

Mass of an electron $= 9.1 \times 10^{- 28}$ g
1 mole $= 6.02 \times 10^{23}$ electrons
$∴$ molar mass of electron $= (9.1 \times 10^{- 28}) \times (6.02 \times 10^{23}) = 5.48 \times 10^{- 4}$ g/mole

The molar mass of an electron is:9.108×10−28 kg/mol6.023×1023 g/mol5.486×10−4 g/mol9.108×10−24 g/mol

Mass of an electron =9.1×10−28g1 mole =6.02×1023 electrons∴ molar mass of electron =(9.1×10−28)×(6.02×1023)=5.48×10−4 g/mole

The molar mass of an electron is:
$9.108 \times 10^{- 28}$ kg/mol
$6.023 \times 10^{23}$ g/mol
$5.486 \times 10^{- 4}$ g/mol
$9.108 \times 10^{- 24}$ g/mol

Mass of an electron $= 9.1 \times 10^{- 28}$ g
1 mole $= 6.02 \times 10^{23}$ electrons
$∴$ molar mass of electron $= (9.1 \times 10^{- 28}) \times (6.02 \times 10^{23}) = 5.48 \times 10^{- 4}$ g/mole
