Question

The mass of a proton is _____ times the mass of an electron.

Answer 1

The mass of the proton = 1.67 x 10^-27 Kg

The mass of the electron = 9.1 x 10^-31 Kg

On taking the ratio of mass proton to mass of electrons.

$\begin{array}{rcl}& =& \frac{1.67\times {10}^{-27}\mathrm{Kg}}{9.1\times {10}^{-31}\mathrm{Kg}}\\ & =& 1835.164\approx 1836\end{array}$

Hence, The mass of a proton is 1836 times the mass of an electron
