The molar mass of any element can be determined by finding the atomic mass of the element on the periodic table. Thus, the molar mass of bilirubin can be expressed as 584.73 g/mol, which is read as “five hundred eighty four point seventy three grams per mole. One 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 division sign (/) implies “per,” and “1” is implied in the denominator. For example, the molar mass of Ba(OH) 2 requires the sum of 1 mass of Ba, 2 masses of O, and 2 masses of H: The molar mass of Ba(OH)2 requires the sum of 1 mass of Ba, 2 masses of O, and 2 masses of H: 1 Ba molar mass:īecause molar mass is defined as the mass for 1 mol of a substance, we can refer to molar mass as grams per mole (g/mol). In formulas with polyatomic ions in parentheses, the subscript outside the parentheses is applied to every atom inside the parentheses.

What is the mass of 1 mol of each substance? The molar mass of any substance is its atomic mass, molecular mass, or formula mass in grams per mole.
