The molar mass of Cesium Chloride (CsCl) can be calculated by adding the atomic masses of Cesium (Cs) and Chlorine (Cl).

Atomic mass of Cesium (Cs): 132.9054519 g/mol

Atomic mass of Chlorine (Cl): 35.453 g/mol

Molar mass of Cesium Chloride (CsCl) = Atomic mass of Cesium + Atomic mass of Chlorine

= 132.9054519 g/mol + 35.453 g/mol

= 168.3584519 g/mol

Therefore, the molar mass of Cesium Chloride (CsCl) is approximately 168.358 g/mol.
