Estimation of Atomic Mass from Specific Heat Data
... Before the development of mass spectrometry, it was difficult to determine the atomic mass of an element. In 1819, Dulong and Petit discovered that the product (about 26.4) of the atomic mass and the specific heat was nearly the same for many solid elements. This approximation has been found to be v ...
