CHEMISTRY GLOSSARY molar mass molarna masa Molar mass is the mass of one mole of a substance. M= mn It is normally expressed in units of g mol-1, in which case its numerical value is identical with the relative molecular mass.
As molar mass and atomic mass are equal for individual atoms, molar mass can be used to measure the particle's identity. For example, the atomic mass of He is 4. Helium is found as monoatomic in nature, meaning that it has only one atom, so its molar mass is also 4....
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
