Question

What is different between molar mass and molecular mass ?

Answer 1

Molar mass and molecular weight are often confused, but their values are very different. Molar mass is the mass of one mole of a substance, while molecular weight is the mass of one molecule of a substance. One mole is the number of particles, such as atoms, molecules, ions or electrons, in a substance.
