The molecular weight of Cesium chloride (RuCl) is 168.35815196.
To calculate molecular weight of any compound, the first step is to know the constituent elements (atoms) and their number in that particular compound. Then calculate the total atomic weight of each element by multiplying its atomic weight by its number. The sum of total atomic weight of all constituent elements will be the molecular weight of the compound. Note that the value of atomic weight may differ from different sources.
CALCULATION PROCEDURE
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Cesium chloride molecule.
From the chemical formula, you will know different atoms and their number in a Cesium chloride molecule. Chemical formula of Cesium chloride is CsCl. From the chemical formula of Cesium chloride, it is easy to find out that there are one Cesium (Cs) atom and one Chlorine (Cl) atom in a molecule of Cesium chloride.
Step 2: Find out atomic weights of each atom (from periodic table).
Atomic weight of Cesium (Cs): 132.90545196 (Ref: Pubchem-Cesium, Ciaaw-Caesium)
Atomic weight of chlorine (Cl) : 35.4527 (Ref: Pubchem-Chlorine, Jlab-ele003)
Step 3: Calculate the molecular weight of Cesium chloride by adding the total weight of all atoms.
Number of Cesium atoms in Cesium chloride: 1
Atomic weight of Cesium: 132.90545196
Total weight of Cesium atoms in Cesium chloride: 132.90545196 x 1 = 132.90545196
Number of Chlorine atoms in Cesium chloride: 1
Atomic weight of Chlorine: 35.4527
Total weight of Chlorine atoms in Cesium chloride: 35.4527 x 1 = 35.4527
Step 4: Calculate the molecular weight of Cesium chloride by adding up the total weight of all atoms.
Molecular weight of Cesium chloride (CsCl):
132.90545196 (Cesium) + 35.4527 (Chlorine)
So the molecular weight of Cesium chloride is 168.35815196.
