# BCl3 (Boron trichloride) Molar Mass (With Calculations)

Molar mass of BCl3 (Boron trichloride) is 117.16 g/mol.

Well, now you have come to know the molar mass of BCl3.

But how can you get this value?

Let me show you the calculation to get the molar mass of BCl3 (Boron trichloride).

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

## BCl3 (Boron trichloride) Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of BCl3 (Boron trichloride).

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 BCl3 (Boron trichloride).

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 BCl3, there is 1 Boron atom and 3 Chlorine atoms.

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

You can see that;

The molar mass of Boron is 10.81 g/mol. [1]

The molar mass of Chlorine is 35.45 g/mol. [2]

Now, to calculate the molar mass of BCl3, you just have to add the molar mass of all the individual atoms that are present in BCl3.

You can see that in BCl3, there is 1 Boron atom and 3 Chlorine atoms.

So, Molar mass of BCl3 = Molar mass of 1 Boron (B) atom + Molar mass of 3 Chlorine (Cl) atoms.
= 10.81 + (35.45) 3
= 10.81 + 106.35
= 117.16 g/mol

Hence the Molar mass of BCl3 is 117.16 g/mol.

I hope you have understood the short and simple calculation for finding the molar mass of BCl3.

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.
