Question

The mass of a dust particle is approximately 7.5 x 10 to the negative 10 kgs and the mass of an electron is 9.1 x 10 to the power of negative 31

Approximately how many electrons have the same mass as one dust particle?

Answer 1

Step-by-step explanation:

Divide the mass of one dust particle by the mass of one electron, and that will be your answer.

 

(7.5 x 10-10 kg) / (9.1 x 10-31 kg) ≅ 8.24 x 1020

Answer 2

Answer:
