Question

Calculate the no of electrons which will together weigh 1 gram

Answer 1

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) = 0.1098 × 10–3 + 31 = 0.1098 × 1028 = 1.098 × 1027

Answer 2

Hey mate here is the answer,
Mass of one electron = 9.10939×10^-31 kg
Number of electrons that weight 9.10939×10^-31 kg= 1
Number of electrons that weight 1 gram=(1×10^-3 kg)
=0.1098×10^-3+31
=0.1098×10^28
=1.098×10^27
Hope this could be the answer.
If this helps then plz mark me BRAINLIEST :-)
