NaN3 (Sodium azide) Molar Mass (With Calculations)

NaN3 (Sodium azide) Molar Mass

Molar mass of NaN3 (Sodium azide) is 65.011 g/mol.

Well, now you have come to know the molar mass of NaN3.

But how can you get this value?

Let me show you the calculation to get the molar mass of NaN3 (Sodium azide).

You can also refer to this one minute video which will show you the simple steps to calculate the molar mass of any compounds.

NaN3 (Sodium azide) Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of NaN3 (Sodium azide).

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 NaN3 (Sodium azide).

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 NaN3, there is 1 Sodium atom and 3 Nitrogen atoms.

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

You can see that;

The molar mass of Sodium is 22.990 g/mol. [1]

The molar mass of Nitrogen is 14.007 g/mol. [2]

Now, to calculate the molar mass of NaN3, you just have to add the molar mass of all the individual atoms that are present in NaN3.

You can see that in NaN3, there is 1 Sodium atom and 3 Nitrogen atoms.

So, Molar mass of NaN3 = Molar mass of 1 Sodium (Na) atom + Molar mass of 3 Nitrogen (N) atoms.
= 22.990 + (14.007) 3
= 22.990 + 42.021
= 65.011 g/mol

Hence the Molar mass of NaN3 is 65.011 g/mol.

I hope you have understood the short and simple calculation for finding the molar mass of NaN3.


  • 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.
