Question

Mass of electron is 9.11*10^-28. How many electons would be required to make 1gram of mass

Answer 1

Answer:

109. 76x 10^25

Explanation:

Given : mass of an electron=9.11 x 10⁻³¹kg =9.11 x 10⁻²⁸g

Number of electrons present in 1g will be : =1/9.11 x 10^28 =109.76 x 10^25

∴ Number of electrons present in 1g would be 109. 76x 10^25 electrons.
