What is the Molar Mass of Barium Chloride

What is the Molar Mass of Barium Chloride (BaCl2)?

The molar mass of a particular substance is described as the mass of the substance’s one mole where a value of 12gmol-1 is assigned to a carbon 12 isotope. Similar to other barium salts that are soluble in water, BaCl2 is highly toxic, and white and imparts a yellowish-green flame coloration. Further BaCl2 is hygroscopic which is first converted to BaCl2(H2O)2. Its use in industry and laboratory is quite limited. 

In this context, it should be mentioned that molar mass is an important term in the subject of chemistry. The molar mass of a substance is denoted by M and has huge importance in the different chemical calculations. The molar mass of any substance can be calculated from the atomic mass of its substance. Similarly, the molar mass of Barium chloride can be calculated. For calculating the molar mass of BaCl2 the atomic mass of Ba and Cl2 are added. Atomic mass of Ba ios 137.327 g/mol whereas that of Cl2 is 35.453 * 2 = 70.906 g/mol. Hence the molar mass of BaCl2 is given as 70.906 g/mol + 137.327 g/mol = 208.233 g/mol.

BaCl2 also has some properties that make it unique. It normally crystallizes in 2 main forms. One form has the Orthorombic Cotunnite structure which is the structure of PbCl2 whereas the other has cubic fluorite or CaF2 structure. BaCl2 behaves in the form of a simple salt in an aqueous solution and it shows a pH in an aqueous solution.
