the mass of a dust particle is approximately 7.5 × 10^-10 kilograms and the mass of an eletron is 9.1×10^-31 kilograms.Approximately how many electrons have the same mass as one dust particle.

Respuesta :

MrEquation
It will take 8.2 x 10^20 electrons to have the same mass as one dust particle.

To get this answer, we divided the mass of the dust particle by the mass of the electron.

7.5 x 10^-10 divided by 9.1 x 10^-31 is 8.2 x 10^20
