**Molar mass of Aluminum nitrate [Al(NO3)3] is ****212.994 g/mol****.**

Well, now you have come to know the molar mass of Al(NO3)3.

But how can you get this value?

Let me show you the calculation to get the molar mass of Aluminum nitrate [Al(NO3)3].

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

## Aluminum nitrate [Al(NO3)3] Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of Aluminum nitrate [Al(NO3)3].

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 Al(NO3)3.

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 Al(NO3)3, there are Aluminum atom, Nitrogen atoms and Oxygen atoms.

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

You can see that;

The molar mass of Aluminum is **26.982 g/mol**. ^{[1]}

The molar mass of Nitrogen is **14.007 g/mol**. ^{[2]}

The molar mass of Oxygen is **15.999 g/mol**. ^{[3]}

Now, to calculate the molar mass of Al(NO3)3, you just have to add the molar mass of all the individual atoms that are present in Al(NO3)3.

**So, Molar mass of Aluminum nitrate [Al(NO3)3] = (Molar mass of Aluminum atom) + {Molar mass of Nitrogen atom + (Molar mass of Oxygen atom) × 3} × 3****= (26.982) + {14.007 + (15.999) × 3} × 3****= (26.982) + {14.007 + 47.997} × 3****= (26.982) + {62.004} × 3****= (26.982) + {186.012}****= 212.994 g/mol**

**Hence the Molar mass of Al(NO3)3 is ****212.994 g/mol****.**

I hope you have understood the short and simple calculation for finding the molar mass of Al(NO3)3.

**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.
