# NH3 (Ammonia) Molar Mass (With Calculations)

Molar mass of NH3 (Ammonia) is 17.031 g/mol.

Well, now you have come to know the molar mass of NH3.

But how can you get this value?

Let me show you the calculation to get the molar mass of NH3 (Ammonia).

If you are a visual learner like me, then here is a short one minute video for you.

## NH3 (Ammonia) Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of NH3 (Ammonia).

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 NH3 (Ammonia).

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 NH3, there is 1 Nitrogen atom and 3 Hydrogen atoms.

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

You can see that;

The molar mass of Nitrogen is 14.007 g/mol. [1]

The molar mass of Hydrogen is 1.008 g/mol. [2]

Now, to calculate the molar mass of NH3, you just have to add the molar mass of all the individual atoms that are present in NH3.

You can see that in NH3, there is 1 Nitrogen atom and 3 Hydrogen atoms.

So, Molar mass of NH3 = Molar mass of 1 Nitrogen (N) atom + Molar mass of 3 Hydrogen (H) atoms.
= 14.007 + (1.008) 3
= 14.007 + 3.024
= 17.031 g/mol

Hence the Molar mass of NH3 is 17.031 g/mol.

I hope you have understood the short and simple calculation for finding the molar mass of NH3.

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.
