How many grams are there in 7.50 x 10^23 molecules of h2so4

123 g

Explanation:

1 mole of H₂SO₄ contains 6.02 × 10²³ molecules of H₂SO₄ (Avogadro's number). The moles of H₂SO₄ represented by 7.50 × 10²³ molecules of H₂SO₄ are:

7.50 × 10²³ molecules × (1 mol/ 6.02 × 10²³ molecules) = 1.25 mol

The molar mass of H₂SO₄ is 98.08 g/mol. The mass of H₂SO₄ represented by 1.25 mol is:

1.25 mol × (98.08 g/mol) = 123 g
