No, we cannot identify a certain element solely by its atomic mass or weight without knowing its chemical formula or additional information. Atomic mass or weight alone does not provide enough information to determine the specific element.
The atomic mass or weight represents the average mass of all the isotopes of an element, taking into account their relative abundance. Many elements have isotopes with different numbers of neutrons, which results in different atomic masses. For example, chlorine has two major isotopes: chlorine-35 and chlorine-37, with atomic masses of approximately 35 and 37 atomic mass units, respectively.
Without knowing the specific chemical formula or additional characteristics of the element, it is not possible to definitively identify the element based solely on its atomic mass or weight.
