Ammonium sulfate Molar Mass (With Calculations)

Molar mass of Ammonium sulfate [(NH4)2SO4] is 132.134 g/mol.

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

But how can you get this value?

Let me show you the calculation to get the molar mass of Ammonium sulfate [(NH4)2SO4].

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

Ammonium sulfate Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of Ammonium sulfate ((NH4)2SO4).

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 Ammonium sulfate ((NH4)2SO4).

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 Ammonium sulfate ((NH4)2SO4), there are Nitrogen atoms, Hydrogen atoms, Sulfur atoms and Oxygen atoms.

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

You can see that;

The molar mass of Nitrogen is 14.007 g/mol. ^[1]

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

The molar mass of Sulfur is 32.06 g/mol. ^[3]

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

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

So, Molar mass of Ammonium sulfate ((NH4)2SO4) = {Molar mass of Nitrogen atom + (Molar mass of Hydrogen atom × 4)} × 2 + Molar mass of Sulfur atom + Molar mass of Oxygen atom × 4
= {14.007 + (1.008 × 4)} × 2 + 32.06 + (15.999) 4
= {14.007 + (4.032)} × 2 + 32.06 + 63.996
= {18.039} × 2 + 32.06 + 63.996
= 36.078 + 32.06 + 63.996
= 132.134 g/mol

Hence the Molar mass of Ammonium sulfate is 132.134 g/mol.

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

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.
