One sulfuric (H2SO4) molecule has 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms.
You can also say one mole of sulfuric acid has two mols of hydrogen atoms, 1 mol of sulfur atoms, and 4 moles of oxygen atoms.
So in total, we have 7 mols of atoms. But that's in 1 mol of sulfuric acid. In two mols of sulfuric acids we have 14 mols of atoms.
How much is a mol? That's the Avogadro's constant = 6.022 x 10^23
So the answer is 14 x 6.022 x 10^23 = 8.43 x 10^24 atoms

since no. of atoms present in H2SO4= no. of moles × avogadros no.
= 2.5 × 6.022 × 10²³
= 15.055 × 10²³ atoms
now no. of sulphur atoms= no. of atoms × 10²³× 1 ( since there is only one sulphur atom in H2SO4)
= 15.055 ×10²³× 1
=15.055 ×10²³ atoms
hope this helps
