Answer

Explanation:

Step1: Recall the pH formula

The formula for pH is $pH = -\log[H_3O^+]$, where $[H_3O^+]$ is the hydronium - ion concentration. We can re - arrange this formula to solve for $[H_3O^+]$: $[H_3O^+]=10^{-pH}$.

Step2: Substitute the given pH value

Given that $pH = 3.60$, we substitute this value into the formula $[H_3O^+]=10^{-pH}$. So, $[H_3O^+]=10^{- 3.60}$. Using a calculator, $10^{-3.60}=2.51\times10^{-4}\ M\approx2.5\times10^{-4}\ M$.

Answer:

A. $2.5\times 10^{-4}\ M$
