Question

The mass of a proton is __________________times that of an electron.

Answer 1

The absolute mass of an electron =$9.109\times {10}^{-28}\mathrm{g}$

The absolute mass of a proton =$1.6725\times {10}^{-24}\mathrm{g}$

$\frac{\mathrm{mass}\mathrm{of}\mathrm{an}\mathrm{electron}}{\mathrm{mass}\mathrm{of}\mathrm{a}\mathrm{proton}}=\frac{9.109\times {10}^{-28}\mathrm{g}}{1.6725\times {10}^{-24}\mathrm{g}}=\frac{1}{1837}$.

The mass of a proton is 1837 times that of an electron.
