Ni(OH)2 Molar Mass (With Calculations)

Ni(OH)2 Molar Mass

Molar mass of Ni(OH)2 is 92.707 g/mol.

Well, now you have come to know the molar mass of Ni(OH)2.

But how can you get this value?

Let me show you the calculation to get the molar mass of Ni(OH)2.

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

Ni(OH)2 Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of Ni(OH)2.

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 Ni(OH)2.

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 Ni(OH)2, there are Nickel atom, Oxygen atoms and Hydrogen atoms.

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

You can see that;

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

The molar mass of Oxygen is 15.999 g/mol. [2]

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

Now, to calculate the molar mass of Ni(OH)2, you just have to add the molar mass of all the individual atoms that are present in Ni(OH)2.

So, Molar mass of Ni(OH)2 = (Molar mass of Nickel atom) + (Molar mass of Oxygen atom + Molar mass of Hydrogen atom) × 2
= (58.693) + (15.999 + 1.008) × 2
= (58.693) + (17.007) × 2
= (58.693) + (34.014)
= 92.707 g/mol

Hence the Molar mass of Ni(OH)2 is 92.707 g/mol.

I hope you have understood the short and simple calculation for finding the molar mass of Ni(OH)2.


  • 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.
