Approx. 2.1×1024 individual atoms.................

Explanation:

We know that in the ONE MOLECULE, the ONE FORMULA UNIT of sulfuric acid, there are 7 atoms: 4×O;2×H; 1×S.

We also that know that in a molar quantity of sulfuric acid, i.e. a 98.08⋅g mass there are NA individual formula units, where NA=Avocado's number=6.022×1023⋅mol−1.

And thus number of atoms, =7⋅atoms×49⋅g98.08⋅g⋅mol−1×6.022×1023⋅mol−1=??atoms.....
