10 mL of a strong acid solution of `pH=2.000` are mixed with 990mL of another strong acid solution of `pH=4.000`. The pH of the resulting solution will be:

Options

A. `3`
B. `3.3`
C. `3.7`
D. Molecular formula of both strogn acids should be known to answer above question.

Explanation

To solve the problem of finding the pH of the resulting solution when mixing two strong acid solutions, we can follow these steps:

### Step 1: Calculate the concentration of H⁺ ions in the first solution.
The pH of the first solution is given as 2.00. We can find the concentration of H⁺ ions using the formula:

\[ [H^+]_1 = 10^{-\text{pH}} = 10^{-2} \, \text{M} \]
