The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams. ›› Lead molecular weight. Molar mass of Pb = 207.2 g/mol. Convert grams Lead to moles or moles Lead to grams ›› Percent composition by element 119 rows ››More information on molar mass and molecular weight. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all … Osmium 22.6 g/cm^3.

Chem. Soc., 1914, cv., 1402) I gave an account in NATURE, It was found that all of the radioactive specimens possess a lower atomic weight than ordinary lead, as determined under identical conditions, the deficiency in one case amounting to as much as 0.75 of a unit. No simple linear quantitative relationship between the exact amount of radioactivity and the atomic weight was found.

Chemists and Chemistry (A series of books devoted to the examination of the history and development of chemistry from its early emergence as a separate discipline to the present day. The isotopic composition and atomic weight of lead are variable in terrestrial materials because its three heaviest stable isotopes are stable end-products of the radioactive decay of uranium (238U to 206Pb; 235U to 207Pb) and thorium (232Th to 208Pb).
