**Molar mass of CrCl3 is ****158.346 g/mol****.**

Well, now you have come to know the molar mass of CrCl3.

But how can you get this value?

Let me show you the calculation to get the molar mass of CrCl3.

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

## CrCl3 Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of CrCl3.

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 CrCl3.

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 CrCl3, there is 1 Chromium atom and 3 Chlorine atoms.

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

You can see that;

The molar mass of Chromium is **51.996 g/mol**. ^{[1]}

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

Now, to calculate the molar mass of CrCl3, you just have to add the molar mass of all the individual atoms that are present in CrCl3.

You can see that in CrCl3, there is 1 Chromium atom and 3 Chlorine atoms.

**So, Molar mass of CrCl3 = Molar mass of 1 Chromium (Cr) atom + Molar mass of 3 Chlorine (Cl) atoms.****= 51.996 + (35.45) 3****= 51.996 + 106.35****= 158.346 g/mol**

**Hence the Molar mass of CrCl3 is ****158.346 g/mol****.**

I hope you have understood the short and simple calculation for finding the molar mass of CrCl3.

**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.
