Question

How much sulphuric acid (H₂SO4) can be
obtained from 5 kg of pure sulphur (58) ?​

Answer 1

Answer:

15.3125 kg

Explanation:

Very simple.

We know that sulphur is SS. We also know that sulphuric acid is H2SO4H2SO4.

So, theoretically, every atom of sulphur can be converted to a molecule of sulphuric acid. So, 1 mol S1 mol S gives 1 mol H2SO41 mol H2SO4.

5000 g S×132mol Sg S=156.25 mol S5000 g S×132mol Sg S=156.25 mol S.

So, we can theoretically get 156.25 mol H2SO4156.25 mol H2SO4, which is:

156.25 mol H2SO4×981g H2SO4mol H2SO4=15.3125 kg H2SO4156.25 mol H2SO4×981g H2SO4mol H2SO4=15.3125 kg H2SO4.

Note: You’ll probably never actually get a 100% yield. Also, the sulphuric acid produced won’t be 100% H2SO4H2SO4, if you refer to the methods of producing it.
