Here's how to calculate the number of moles in 1 g of H₂SO₄:

1. Find the molar mass of H₂SO₄:

* H (Hydrogen): 1.01 g/mol * 2 = 2.02 g/mol

* S (Sulfur): 32.07 g/mol

* O (Oxygen): 16.00 g/mol * 4 = 64.00 g/mol

Total molar mass of H₂SO₄ = 2.02 + 32.07 + 64.00 = 98.09 g/mol

2. Use the formula:

* Moles = Mass / Molar Mass

* Moles = 1 g / 98.09 g/mol

* Moles ≈ 0.0102 mol

Therefore, there are approximately 0.0102 moles present in 1 gram of H₂SO₄.
