Answer:

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

The mass of 7.5 x 10²³ molecules of H₂SO₄ is 122.5 g.

Avogadro's number

One mole of a substance contains 6.02 x 10²³ molecules of the substance.

6.02 x 10²³ molecules --------------- one mole of H₂SO₄

7.5 x 10²³ molecules --------------------- ?

[tex]x = \frac{7.5 \times 10^{23}}{6.02 \times 10^{23}} \\\\x = 1.25 \ moles[/tex]

Mass of H₂SO₄

1 mole ------ 98 g/mol

1.25 moles ----- ?

= 1.25 x 98

= 122.5 g

Thus, the mass of 7.5 x 10²³ molecules of H₂SO₄ is 122.5 g.
