Webatomic weight, also called relative atomic mass, ratio of the average mass of a chemical element’s atoms to some standard. Since 1961 the standard unit of atomic mass has been one-twelfth the mass of an atom of the isotope carbon-12. An isotope is one of two or more species of atoms of the same chemical element that have different atomic mass … WebSn (CO3)2 molecular weight Molar mass of Sn (CO3)2 = 238.7278 g/mol Convert grams Sn (CO3)2 to moles or moles Sn (CO3)2 to grams Molecular weight calculation: 118.71 + (12.0107 + 15.9994*3)*2 Percent composition by element Similar chemical formulas Note that all formulas are case-sensitive.
