Calculate the mass of HCl present per litre of the solution whose pH value is 1.301.

Explanation

To calculate the mass of HCl present per liter of a solution with a pH value of 1.301, we can follow these steps:

### Step 1: Understand the relationship between pH and H⁺ concentration
The pH of a solution is related to the concentration of hydrogen ions (H⁺) by the formula:
\[ \text{pH} = -\log[H^+] \]

### Step 2: Calculate the H⁺ concentration from the given pH
Given the pH value of 1.301, we can rearrange the formula to find [H⁺]:
...
