1. Determine the Molecular Formula and Molar Mass of Sulfuric Acid

* Sulfuric acid has the formula H₂SO₄.

* Its molar mass is:

* (2 x 1.008 g/mol H) + (32.066 g/mol S) + (4 x 15.999 g/mol O) = 98.079 g/mol

2. Calculate the Number of Moles of Sulfuric Acid

* Divide the given mass by the molar mass:

* 17.9325 g / 98.079 g/mol = 0.183 mol H₂SO₄

3. Calculate the Number of Moles of Oxygen Atoms

* There are 4 oxygen atoms per molecule of H₂SO₄:

* 0.183 mol H₂SO₄ x (4 mol O / 1 mol H₂SO₄) = 0.732 mol O

4. Calculate the Number of Oxygen Atoms

* Use Avogadro's number (6.022 x 10²³ atoms/mol) to convert moles to atoms:

* 0.732 mol O x (6.022 x 10²³ atoms/mol) = 4.41 x 10²³ atoms of oxygen

Therefore, there are approximately 4.41 x 10²³ atoms of oxygen in 17.9325g of sulfuric acid.
