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

Explanation

To determine how many moles of hydrogen are present in 4.9 g of \( H_2SO_4 \) (sulfuric acid), we can follow these steps:

### Step 1: Calculate the Molecular Weight of \( H_2SO_4 \)

The molecular formula of sulfuric acid is \( H_2SO_4 \). To find the molecular weight, we need to sum the atomic weights of all the atoms in the formula:

- Hydrogen (H): 2 atoms × 1 g/mol = 2 g/mol
- Sulfur (S): 1 atom × 32 g/mol = 32 g/mol
