Sorry I mistakenly wrote 298 instead of 294 grams so replace the 298 g in the solution with 294 and calculate you'd get the answer, if not comment and I will provide the solution once more.

______________
H2SO4-----------------> H+ +HSO4_
1 mole H2SO4 forms 1 mole Hydrogen atom
Mass of H2SO4 = 294g
Molar mass of H2SO4 = 1×2 + 32 + 16×4
Molar mass of H2SO4 = 34 + 64
Molar mass of H2SO4 = 98 g/mol
Moles of H2SO4 =mass /molar mass
Moles of H2SO4 = 294/98
Moles of H2SO4 =3mol
So 3 mole will produce 3 mole hydrogen atom
1mole = 6.023×10^23
So 3 mole hydrogen atom = 3×6.023×10^23
Number of hydrogen atoms = 18.069 ×10^23
