a. What amount of `H_(2)SO_(4)` must be dissolved in `500mL` of solution to have a `pH` of `2.15`?

Explanation

To determine the amount of `H₂SO₄` that must be dissolved in `500 mL` of solution to achieve a `pH` of `2.15`, follow these steps:

### Step 1: Understand the relationship between pH and hydrogen ion concentration
The pH of a solution is defined as:
\[ \text{pH} = -\log[H^+] \]
Where \([H^+]\) is the concentration of hydrogen ions in moles per liter (M).

### Step 2: Calculate the hydrogen ion concentration
