Question

if the mass of the electron is 9.11×10^31 kg then its mass is of the order ​

Answer 1

Answer:

If one mass of one electron is 9.11 x 10−31kg, then how many electrons would weigh in 1 kg? Answer: Given : mass of an electron=9.11 x 10⁻³¹kg =9.11 x 10⁻²⁸g 1kg=1000g Number of electrons present in 1kg will be : =1000/9.11 x 10⁻²⁸ =109.76 x 10 ²⁸ ∴ Number of electrons present in 1kg would be 109
