How many moles are im 8.31x1023 molecules of h2so4

1.38 mol.

Explanation:

Using cross multiplication:

1.0 mole of H₂SO₄ contains → 6.022 x 10²³ molecules.

??? moles of H₂SO₄ contains → 8.31 x 10²³ molecules.

∴ The no. of moles in (8.31 x 10²³ molecules) of H₂SO₄ = (1.0 mol)(8.31 x 10²³) / (6.022 x 10²³ molecules) = 1.38 mol.
