Question

Find no. Of sulphur molecules in 4.9 gm of H2SO4

Answer 1

1 mole of H₂SO₄  have 1 mole of sulphur

no of moles of H₂SO₄ = 4.9/98

                                    = 0.05moles

0.05 moles of H₂SO₄ contains 0.05 moles of sulphur

so no  fo sulphur atoms = 0.05×avogadro no

                                        =0.05×6.022×10²³=3×10²²

Answer 2

Answer:

no of sulphur atoms ==0.05×6.022×10²³=3×10²

Explanation:

1 mole of H₂SO₄  have 1 mole of sulphur

no of moles of H₂SO₄ = 4.9/98

                                   = 0.05moles

0.05 moles of H₂SO₄ contains 0.05 moles of sulphur

so no  fo sulphur atoms = 0.05×avogadro no

                                       =0.05×6.022×10²³=3×10²
