CuCO3 (Cupric carbonate) Molar Mass (With Calculations)

CuCO3 (Cupric carbonate) Molar Mass

Molar mass of CuCO3 (Cupric carbonate) is 123.554 g/mol.

Well, now you have come to know the molar mass of CuCO3.

But how can you get this value?

Let me show you the calculation to get the molar mass of CuCO3 (Cupric carbonate).

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

CuCO3 (Cupric carbonate) Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of CuCO3 (Cupric carbonate).

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 CuCO3 (Cupric carbonate).

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 CuCO3, there is 1 Copper atom, 1 Carbon atom and 3 Oxygen atoms.

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

You can see that;

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

The molar mass of Carbon is 12.011 g/mol. [2]

The molar mass of Oxygen is 15.999 g/mol. [3]

Now, to calculate the molar mass of CuCO3, you just have to add the molar mass of all the individual atoms that are present in CuCO3.

You can see that in CuCO3, there is 1 Copper atom, 1 Carbon atom and 3 Oxygen atoms.

So, Molar mass of CuCO3 = Molar mass of 1 Copper (Cu) atom + Molar mass of 1 Carbon (C) atom + Molar mass of 3 Oxygen (O) atoms.
= 63.546 + 12.011 + (15.999) 3
= 63.546 + 12.011 + 47.997
= 123.554 g/mol

Hence the Molar mass of CuCO3 is 123.554 g/mol.

I hope you have understood the short and simple calculation for finding the molar mass of CuCO3.


  • 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.
