Question

The mass of an electron is 9.11 × 10^-31 kg. how many electrons would make 1 kg

Answer 1

Answer:

Explanation:

m of an electron = 9.11 × 10^-31 kg

m = 1 kg

No. of electrons = $\frac{m}{mass of electron}$

                           = $\frac{1}{9.11 x 10^{-31} }$

                           = 1.1 x $10^{30}$ electrons

Answer 2

Explanation:

No of electrons=Total mass/mass of electrons

=1kg/9.11*10-³¹kg

=1000/9.11*1-³¹kg

=1.1*10³⁰
