The first scientists to determine relative atomic masses were John Dalton and Thomas Thomson between 1803 and 1805 and Jöns Jakob Berzelius between 1808 and 1826. Relative atomic mass (Atomic weight) was originally defined relative to that of the lightest element, hydrogen, which was taken as 1.00, and in the 1820s, Prout's hypothesis stated that atomic masses of all elements would prove to be exact multiples of that of hydrogen. Berzelius, however, soon proved that thi… Web13 de jun. de 2015 · You use the formula for density and the published radii to calculate the densities. The values are 6.70 × 10^14"kg/dm"^3 and 2.7"kg/dm"^3. The formulas to use are "Density" = "mass"/"volume" or ρ = m/V and V = (4/3)πr^3 Hydrogen nuclei A hydrogen nucleus is a proton, and the mass of a proton is 1.67 × 10^(-27)"kg". The …
