Molar mass, denoted by ‘k’, represents the mass of one mole of a substance, providing a convenient way to express and compare the mass of chemical entities. Calculated by adding the atomic masses of all atoms in a molecule or formula unit, it serves as a conversion factor between mass and amount, connecting mass in grams to the number of moles. Understanding molar mass allows chemists to convert between mass and quantity, enabling precise calculations in various applications, from determining substance compositions to solving stoichiometry problems.
