Molar mass of H2S is 34.076 g/mol.
Well, now you have come to know the molar mass of H2S.
But how can you get this value?
Let me show you the calculation to get the molar mass of H2S.
If you are a visual learner like me, then here is a short one minute video for you.
H2S Molar Mass Calculation
If you have a periodic table with you, then you can easily calculate the molar mass of H2S.
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 H2S.
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 H2S, there are 2 Hydrogen atoms and 1 Sulfur atom.
So let’s look at the molar mass of Hydrogen and Sulfur from the above periodic table.
You can see that;
The molar mass of Hydrogen is 1.008 g/mol. 
The molar mass of Sulfur is 32.06 g/mol. 
Now, to calculate the molar mass of H2S, you just have to add the molar mass of all the individual atoms that are present in H2S.
You can see that in H2S, there are 2 Hydrogen atoms and 1 Sulfur atom.
So, Molar mass of H2S = Molar mass of 2 Hydrogen (H) atoms + Molar mass of 1 Sulfur (S) atom.
= (1.008) 2 + 32.06
= 2.016 + 32.06
= 34.076 g/mol
Hence the Molar mass of H2S is 34.076 g/mol.
I hope you have understood the short and simple calculation for finding the molar mass of H2S.
- 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.
