GENERAL KNOWLEDGE

Detailed explanation-1: -The molar mass of an element is the mass in grams of one mole (6.02 x 1023 particles) of the element. So in most cases, to find the molar mass of an element, you just need to look at its atomic mass (atomic weight) on the periodic table. Remember-that’s the number written under the element symbol and element name.

Detailed explanation-2: -The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

Detailed explanation-3: -Molar mass is not a detail included on the periodic table of elements because molar mass measures the mass of molecules and not atoms. As only individual atoms of elements are listed on the periodic table, only the atomic mass will be listed.

Detailed explanation-4: -On the periodic table, the mass number is usually located below the element symbol. The mass number listed is the average mass of all of the element’s isotopes.
