MgBr2 (Magnesium bromide) Molar Mass (With Calculations)

Molar mass of MgBr2 (Magnesium bromide) is 184.113 g/mol.

Well, now you have come to know the molar mass of MgBr2.

But how can you get this value?

Let me show you the calculation to get the molar mass of MgBr2 (Magnesium bromide).

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

MgBr2 (Magnesium bromide) Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of MgBr2 (Magnesium bromide).

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 MgBr2 (Magnesium bromide).

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 MgBr2, there is 1 Magnesium atom and 2 Bromine atoms.

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

You can see that;

The molar mass of Copper is 63.546 g/mol. ^[1]

The molar mass of Bromine is 79.904 g/mol. ^[2]

Now, to calculate the molar mass of MgBr2, you just have to add the molar mass of all the individual atoms that are present in MgBr2.

You can see that in MgBr2, there is 1 Magnesium atom and 2 Bromine atoms.

So, Molar mass of MgBr2 = Molar mass of 1 Magnesium (Mg) atom + Molar mass of 2 Bromine (Br) atoms.
= 24.305 + (79.904) 2
= 24.305 + 159.808
= 184.113 g/mol

Hence the Molar mass of MgBr2 is 184.113 g/mol.

I hope you have understood the short and simple calculation for finding the molar mass of MgBr2.

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.
