NiCl2 · 6H2O Molar Mass (With Calculations)

Molar mass of NiCl2 · 6H2O is 237.683 g/mol.

Well, now you have come to know the molar mass of NiCl2 · 6H2O.

But how can you get this value?

Let me show you the calculation to get the molar mass of NiCl2 · 6H2O.

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

NiCl2 · 6H2O Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of NiCl2 · 6H2O.

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 NiCl2 · 6H2O.

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 NiCl2 · 6H2O, there is Nickel atom, Chlorine atoms, Hydrogen atoms and Oxygen atoms.

So let’s look at the molar mass of Nickel, Chlorine, Hydrogen and Oxygen from the above periodic table.

You can see that;

The molar mass of Nickel is 58.693 g/mol. ^[1]

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

The molar mass of Hydrogen is 1.008 g/mol. ^[3]

The molar mass of Oxygen is 15.999 g/mol. ^[4]

Now, to calculate the molar mass of NiCl2 · 6H2O, you just have to add the molar mass of all the individual atoms that are present in NiCl2 · 6H2O.

So, Molar mass of NiCl2 · 6H2O = {Molar mass of Nickel atom + (Molar mass of Chlorine atom × 2)} + [6 × {(Molar mass of Hydrogen × 2) + Molar mass of Oxygen}]
= {58.693 + (35.45) 2} + [6 × {(1.008 × 2) + 15.999}]
= {58.693 + 70.9} + [6 × {(2.016) + 15.999}]
= {129.593} + [6 × {18.015}]
= {129.593} + [108.09]
= 237.683 g/mol

Hence the Molar mass of NiCl2 · 6H2O is 237.683 g/mol.

I hope you have understood the short and simple calculation for finding the molar mass of NiCl2 · 6H2O.

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.
