ZnCl2 (Zinc chloride) Molar Mass (With Calculations)

Molar mass of ZnCl2 (Zinc chloride) is 136.28 g/mol.

Well, now you have come to know the molar mass of ZnCl2.

But how can you get this value?

Let me show you the calculation to get the molar mass of ZnCl2 (Zinc chloride).

ZnCl2 (Zinc chloride) Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of ZnCl2 (Zinc chloride).

Because the molar mass of any molecule (or compound) can be calculated by simply adding the molar masses of individual atoms.

Now here we have to find the molar mass of ZnCl2 (Zinc chloride).

So for that, have a look at the periodic table given below.

You can see the molar mass value of all the atoms from this periodic table.

Now in ZnCl2, there is 1 Zinc atom and 2 Chlorine atoms.

So let’s look at the molar mass of Zinc and Chlorine from the above periodic table.

You can see that;

The molar mass of Zinc is 65.38 g/mol. ^[1]

The molar mass of Chlorine is 35.45 g/mol. ^[2]

Now, to calculate the molar mass of ZnCl2, you just have to add the molar mass of all the individual atoms that are present in ZnCl2.

You can see that in ZnCl2, there is 1 Zinc atom and 2 Chlorine atoms.

So, Molar mass of ZnCl2 = Molar mass of 1 Zinc (Zn) atom + Molar mass of 2 Chlorine (Cl) atoms.
= 65.38 + (35.45) 2
= 65.38 + 70.9
= 136.28 g/mol

Hence the Molar mass of ZnCl2 is 136.28 g/mol.

I hope you have understood the short and simple calculation for finding the molar mass of ZnCl2.

Remember

• In some books, you may see the unit of molar mass as grams/mole or g/mole. But all these units (i.e g/mol, grams/mole and g/mole) are the same. 
• Always follow the calculation order to avoid any mistakes in calculation. First solve the brackets, then multiplications and at last do the final addition.
• And don’t forget to put the unit g/mol to your final calculated molar mass.
