Because the definitions of both the mole and the atomic mass unit are based on the same reference substance,12C,the molar mass of any substance is numerically equivalent to its atomic or formula weight in amu. Per the amu definition, a single12C atom weighs 12 amu (its atomic mass is 12 ...

What is the formula to find molar mass? The molar mass is calculated as the product of mass and moles. Molar mass = Mass*Mole Here, the units of mass are grams and the units of moles are mols, so the units of the molar mass will be g/mol. What is molar mass and how is it...

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
