The molecular weight of Strontium Chloride (SrCl₂) is 158.5254.

Strontium chloride (SrCl₂) is an inorganic compound of two elements: Strontium (Sr) and Chlorine (Cl). The molecular weight of Strontium chloride is 158.5254 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements

CALCULATION PROCEDURE

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Strontium Chloride molecule.
From the chemical formula, you will know different atoms and their number in a Strontium Chloride molecule. The chemical formula of Strontium Chloride is SrCl₂. From the chemical formula of Strontium Chloride, it is easy to find out that there are one Strontium (Sr) atom and two Chlorine (Cl) atoms in a molecule of Strontium Chloride.

Step 2: Find out the atomic weights of each atom (from the periodic table).

Atomic weight of Strontium (Sr): 87.62 (Ref: Pubchem-38, Ciaaw-strontium)
Atomic weight of Chlorine (Cl): 35.4527 (Ref: Jlab-ele017)

Step 3: Calculate the molecular weight of Strontium Chloride by adding the total weight of all atoms.

Number of Strontium atoms in Strontium Chloride: 1
Atomic weight of Strontium: 87.62
Total weight of Strontium atoms in Strontium Chloride: 87.62 x 1 = 87.62

Number of Chlorine atoms in Strontium Chloride: 2
Atomic weight of Chlorine: 35.4527
Total weight of Chlorine atoms in Strontium Chloride: 35.4527 x 2 = 70.9054

Step 4: Calculate the molecular weight of Strontium Chloride by adding up the total weight of all atoms.

Molecular weight of Strontium Chloride (SrCl₂): 87.62 (Strontium) + 70.9054 (Chlorine) = 158.5254

So the molecular weight of Strontium Chloride is 158.5254.
