Question

the ratio of mass of an electronic to that of the mass of hydrogen atom is

Answer 1

Electron mass = 9.11*10^-31 kg

Hydrogen atomic mass = 1.67*10–27 kg

Ratio approx 1/1837

Answer 2

Answer:

mass of electron=9.11*10^-31 kg

mass of hydrogen=1.66*10^-31 kg

ratio=mass of electron/mass of

hydrogen

ratio=1:1837
