Type in your own numbers in the form to convert the units! as English units, currency, and other data. We assume you are converting between electronvolt and gram. In 1811, the Italian scientist Amedeo Avogadro realized that the volume of a gas (at a given pressure and temperature) is proportional to the number of atoms or molecules composing it, regardless of which gas it was. The energy can then be used with Einstein's famous equation, E = mc2, to solve for the mass of the atom when it is rearranged to m = E/c2. In the International units ( SI units) 1eV corresponds to 1.6*10^-19 Joules. A reasonably accurate value of the atomic mass unit was first obtained indirectly by Josef Loschmidt in 1865, by estimating the number of particles in a given volume of gas. The mass of an electron is very lighter than the proton and neutron mass as we said it earlier. atomic mass, the quantity of matter contained in an atom of an element. What is the reflection of the story of princess urduja? The electron has a rest mass of 9.1093837015 1031 kg, which is only 1/1,836 that of a proton. In other words, we can say that the characteristics of different atom vary for the total number of the electron in it.
