However, please refer to the probable answer of the query which you have posted-
  • Hydrogen is the atom of lowest mass that is, 1u.
  • The mass of a proton is taken as 1 unit and its charge as +1.
  • The mass of a proton was calculated as being equal to the mass of an atom of hydrogen, i.e. 1·672 x 10-24 g. The relative mass of a proton is 1u.
  • If we compare the mass of a proton with that of an electron, then the mass of a proton is 1840 times that of an electron. 
  • The absolute mass of a proton is 1.6 x 10-24 gram.
