Answer 2

Answer:

The difference in mass between a proton and electron is 1.672*10⁻²⁷ kg

Explanation:

Mass of a proton = $1.673*10^{-24} \ g$

Mass of an electron = $9.11*10^{-28} \ g$

The difference in mass between a proton and electron is:

$[1.673*10^{-24} - 9.11*10^{-28}]g = 1.672*10^{-24}\ g$

Convert g to kg

10³ g = 1 kg

The difference in mass in units of kg would be:

$=\frac{1.672*10^{-24}g * 1 kg }{10^{3}g} = 1.672*10^{-27} kg$
