WebQuestion: Relationship between Specific Heat and Atomic Mass Based on specific heat measurements, Pierre Dulong and Alexis Petit proposed in 1818 that the specific heat of an element is related to its atomic weight (atomic mass). Thus, by measuring the specific heat of a new element, its atomic weight could be readily established. Webspecific heat of a metal is related to its molar mass by a simple relationship. Dulong and Petit discovered that 25 joules is required to raise the temperature of one mole of many …
