Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calcul
To find the molar mass of a compound, you need to add the molar mass of all the elements in that compound. Take a look at NaOH which contains sodium, oxygen and hydrogen. The molar mass of sodium is 22.99 g/mol, oxygen is 15.999 g/mol, and hydrogen is 1.008 g/mol. Adding them t...

Molar mass, sometimes referred to as molecular weight or molecular mass, is equal to the sum of the atomic masses of each element in the compound.[1] The atomic mass is the mass of 1 mol of an atom – so if you add up the atomic masses of all the atoms in the compound, the ...
Molar mass can be defined as 'mass per mole.' In other words, molar mass is the sum of the mass of all the atoms found in one mole's worth of a substance. It is expressed in units of grams per mole. Molar mass is depicted for elements or molecules. In the case of single element...
The molar mass of water is equivalent to the mass of one mole of water molecules. One mole is a scientific form of measurement in chemistry. Elements need to have equal amounts of protons and electrons to be stable, but they can vary in the amount of neutrons they contain. The amount ...

When computing the formula mass of an ionic compound, the average masses of neutral sodium and chlorine atoms were used, rather than the masses for sodium cations and chloride anions. Even though a sodium cation has a slightly smaller mass than a sodium atom (since it is missing an electron...
the mass given in the Periodic Table or table of atomic weights. Multiply the subscript (number of atoms) times theatomic massof that element and add the masses of all of the elements in the molecule to get themolecular mass. Molar mass usually is expressed in grams (g) or kilograms (...
