To find the mass of 3.25 moles of sulfuric acid (H₂SO₄), we need to use the molar mass of H₂SO₄.The molar mass of H₂SO₄ is calculated as follows:- Hydrogen (H): 1.01 g/mol × 2 = 2.02 g/mol- Sulfur (S): 32.07 g/mol × 1 = 32.07 g/mol- Oxygen (O): 16.00 g/mol × 4 = 64.00 g/molAdding these together gives the molar mass of H₂SO₄:
Now, we can calculate the mass of 3.25 moles of H₂SO₄:
Therefore, the closest answer is:C. 316 g
