EDTA (C10H16N2O8) Molar Mass (With Calculations)

Molar mass of EDTA (Ethylenediaminetetraacetic acid or C10H16N2O8) is 292.244 g/mol.

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

But how can you get this value?

Let me show you the calculation to get the molar mass of EDTA (C10H16N2O8).

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

EDTA (C10H16N2O8) Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of EDTA (C10H16N2O8).

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 EDTA (C10H16N2O8).

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 EDTA (C10H16N2O8), there are 10 Carbon atoms, 16 Hydrogen atoms, 2 Nitrogen atoms and 8 Oxygen atoms.

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

You can see that;

The molar mass of Carbon is 12.011 g/mol. ^[1]

The molar mass of Hydrogen is 1.008 g/mol. ^[2]

The molar mass of Nitrogen is 14.007 g/mol. ^[3]

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

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

You can see that in EDTA (C10H16N2O8), there are 10 Carbon atoms, 16 Hydrogen atoms, 2 Nitrogen atoms and 8 Oxygen atoms.

So, Molar mass of EDTA (C10H16N2O8) = Molar mass of 10 Carbon (C) atoms + Molar mass of 16 Hydrogen (H) atoms + Molar mass of 2 Nitrogen (N) atoms + Molar mass of 8 Oxygen (O) atoms.
= (12.011) 10 + (1.008) 16 + (14.007) 2 + (15.999) 8
= 120.11 + 16.128 + 28.014 + 127.992
= 292.244 g/mol

Hence the Molar mass of EDTA (C10H16N2O8) is 292.244 g/mol.

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

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.
