The unit 'amu' is now being replaced by a lower case u, where u is the symbol for the unified atomic mass unit. Therefore one atom of carbon, isotopic mass 12,

Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2. Definitions of molecular mass, molecular weight, molar mass and molar weight. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Atomic Mass.

Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). ›› O molecular weight. Molar mass of O = 15.9994 g/mol. Convert grams O to moles or moles O to grams ›› Percent composition by element The chemists used a "atomic mass unit" (amu) scale such that the natural mixture of oxygen isotopes had an atomic mass 16, while the physicists assigned the same number 16 to only the atomic mass of the most common oxygen isotope (16 O, containing eight protons and eight neutrons).

Atomic Mass Unit. Atomic mass units (u) are used to measure mass of molecules and atoms. 1 u is 1/12 of a mass of an atom of carbon-12. It is about 1.66 × 10⁻²⁷ kilograms. Slug. The slug is a unit of mass used in the imperial system, mainly in the UK. 1 slug is defined as a mass that accelerates by 1 foot per second squared when one pound
