(Number of Moles of Component in Mixture)/(Total Number of Moles in Component) (Mass of Entity present in Substance)/(Total Mass of Substance) (Actual mass of Product)/(Theoretical Mass of Product) (Mass of Substance in Gram)/(Relative Molecular Mass) (Mass of Element in Gram)/(Relative Atomic Mass) Units of Molar Mass: SI unit is kg/ mol or gm/mol.īelow are some of the important formulas regarding molar mass: 1 grams Sodium to mol 0.0435 mol 10 grams Sodium to mol 0.43498 mol 20 grams Sodium to mol 0.86995 mol 30 grams Sodium to mol 1.30493 mol 40 grams Sodium to mol 1.7399 mol 50 grams Sodium to mol 2.17488 mol 100 grams Sodium to mol 4.34976 mol 200 grams Sodium to mol 8. The formula of molar mass is grams per mole. Molar mass is important in the mole concept. The bridge between the substance and the macroscopic level is molar mass. In order to make the measurement of masses more useful and easier, quantities are to be represented on a macroscopic level. However, it becomes difficult to calculate the mass of each particle present in the substance.
We can calculate the mass of atoms, molecules, etc. One mole is also defined as the amount of a substance that contains as many entities as there are atoms in exactly 12 g of the 12C isotope. Even a gram of any pure element contains a high amount of atoms. A mole is defined as the amount of substance containing the same number of different entities (such as atoms, ions, molecules, and compounds) as the number of atoms in a sample of pure 12C weighing precisely 12 g. Mole, also written as mol, is the fundamental unit used to measure the amount of substance. Therefore, for convenient 6.023 × 10 23 is named Avogadro’s Number (N A). One mole of any substance contains the same amount of units i.e. The number of atoms present in 12 grams of C-12 isotope is the number of particles present in 1 mole of the substance.
