Text Solution

AI Generated Solution

To calculate the percentage of sulfur in sulfuric acid (H₂SO₄), we can follow these steps: ### Step 1: Determine the molar mass of sulfur (S) The molar mass of sulfur (S) can be found using the periodic table. - Molar mass of sulfur (S) = 32 g/mol ### Step 2: Determine the molar mass of sulfuric acid (H₂SO₄) To find the molar mass of sulfuric acid, we need to sum the molar masses of all the atoms in the formula H₂SO₄: ...
