9.8 gm of H2SO4 = 9.8/98 = 0.1mole
1 mole = 6.023 x 1023 molecules
0.1 Mole = 6.023 x 1022 molecules.
One molecule of H2SO4 = 2 hydrogen atom, one sulphur atom and 4 oxygen atoms therefore
Number of hydrogen atom in 0.1 mole = 2 x 6.023 x 1022
= 12.046 x 1022
Number of sulphur atom in 0.1 mole = 1 x 6.023 x 1022
= 6.023 x 1022
Number of oxygen atom in 0.1 mole = 4 x 6.023 x 1022
= 24.092 x 1022
