Molar mass of ZnO (Zinc oxide) is 81.379 g/mol.
Well, now you have come to know the molar mass of ZnO.
But how can you get this value?
Let me show you the calculation to get the molar mass of ZnO (Zinc oxide).
You can also refer to this one minute video which will show you the simple steps to calculate the molar mass of any compounds.
ZnO (Zinc oxide) Molar Mass Calculation
If you have a periodic table with you, then you can easily calculate the molar mass of ZnO (Zinc oxide).
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 ZnO (Zinc oxide).
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 ZnO, there is 1 Zinc atom and 1 Oxygen atom.
So let’s look at the molar mass of Zinc and Oxygen from the above periodic table.
You can see that;
The molar mass of Zinc is 65.38 g/mol. 
The molar mass of Oxygen is 15.999 g/mol. 
Now, to calculate the molar mass of ZnO, you just have to add the molar mass of all the individual atoms that are present in ZnO.
You can see that in ZnO, there is 1 Zinc atom and 1 Oxygen atom.
So, Molar mass of ZnO = Molar mass of 1 Zinc (Zn) atom + Molar mass of 1 Oxygen (O) atom.
= 65.38 + 15.999
= 81.379 g/mol
Hence the Molar mass of ZnO is 81.379 g/mol.
I hope you have understood the short and simple calculation for finding the molar mass of ZnO.
- 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.
