How many moles of H, are present in 4.9 g `H_(2)SO_(4)`?

Explanation

To find out how many moles of hydrogen (H) are present in 4.9 g of sulfuric acid (H₂SO₄), we can follow these steps:

### Step 1: Calculate the molar mass of H₂SO₄
- The molar mass of H₂SO₄ can be calculated by adding the molar masses of its constituent elements:
- Hydrogen (H): 1 g/mol (2 atoms in H₂SO₄, so 2 × 1 = 2 g/mol)
- Sulfur (S): 32 g/mol
- Oxygen (O): 16 g/mol (4 atoms in H₂SO₄, so 4 × 16 = 64 g/mol)
