Question

number of hydrogen oxygen and sulphur atoms in 196 gram H2SO4

Answer 1

No. of moles of H₂SO₄ = Mass/Molar mass = 196/98 = 2 moles

1 Mole of H₂SO₄ contains = 1 mole of S atoms = 6.023 x 10²³ atoms of oxygen
1 Mole of H₂SO₄ contains = 2 mole of H atoms = 2 x 6.023 x 10²³ atoms of Hydrogen = 1.2046 x 10²⁴ atoms of H
1 Mole of H₂SO₄ contains = 4 mole of O atoms = ​4 x 6.023 x 10²³ atoms of O atoms = 2.4092 ​ x 10²⁴ atoms of O
