WebOne mole (abbreviated mol) is equal to 6.022×10 23 molecular entities (Avogadro's number), and each element has a different molar mass depending on the weight of 6.022×10 23 of its atoms (1 mole). The molar mass of any element can be determined by finding the atomic mass of the element on the periodic table. WebThat is, the molar mass of a substance is the mass (in grams per mole) of 6.022 × 10 23 atoms, molecules, or formula units of that substance. In each case, the number of grams in 1 mol is the same as the number of atomic mass units that describe the atomic mass, the molecular mass, or the formula mass, respectively.
