Question

Calculate the number of electrons which will together weigh one gram.

Solution

Mass of one electron = 9.10939 × 10–31 kg

∴ Number of electrons that weigh 9.10939 × 10–31 kg = 1

Number of electrons that will weigh 1 g = (1 × 10–3 kg)

`= 1/(9.10939 xx 10^(-31)) xx (1xx10^(-3) kg)`

= 0.1098 × 10–3 + 31

= 0.1098 × 1028

= 1.098 × 1027

  Is there an error in this question or solution?
