   Molar mass is defined as the amount of mass of a chemical substance when formula mass is taken grams. For Example, molar mass of C 6H 12O 6 is 180.18 g since Formula mass of C 6H 12O 6 is 180.18 g/mole. Molar mass contains mole (6.022 x 10 23) of formula (C 6H 12O 6) units. The atomic mass of sodium is 23.0 amu and molar mass is 23.0 g/mol 1 ...

   The mass of one mole of any substance is the same numerical value as the atomic mass given in the periodic table, but it is expressed in grams rather than amus. The mass of one mole of a substance is known as the molar mass. Examples: The atomic mass of Mg is 24.31 amu. This is the mass of one Mg atom.

   Moles = mass of substance relative atomic mass . If we take a mole of ionic lattice or molecules of a material, the mass will be the molar mass . To find the number of moles of molecules or compounds we can use the formula: Moles = mass molar mass (RFM, Mr) Examples . 1. Calculate the number of moles in 10g magnesium sulphate (MgSO. 4.)

   Is molecular mass the same as molar mass?

   • But, they are not exactly the same as each other. First, molecular mass is either unitless or else reported in daltons (Da) or atomic mass units (amu or u). On the other hand, the unit for molar mass is grams per mole (g/mol) or kilograms per mole (kg/mol). Second, molecular mass describes the mass of a single molecule or type of molecule.
