WebExamples 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) WebMassa molar de H₂O = 2 g + 16 g = 18 g/mol. O mol é a unidade usada para converter da unidade de massa atômica (u) para gramas. O valor de 1 mol é igual a aproximadamente 6,022 x 10²³, esse valor foi deduzido para a conversão da massa do átomo, que é expressa em "U", ser igual em gramas. Sendo este conhecido como a Constante de Avogadro .
