Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calcul
To convert between the mass of an element (in grams) and the number of moles, the molar mass of the element (g/mol) is used as a conversion factor. Text adapted from Openstax Chemistry 2e, Section 3.1: Formula Mass and the Mole Concept. Tags Molar Mass Periodic Table Avogadro's Number...
