Answer

Explanation:

Step1: Recall 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 $pH = 4.8$, we substitute this value into the formula $[H_3O^+]=10^{-4.8}$. Using a calculator, $10^{-4.8}\approx1.58\times 10^{-5}$.

Answer:

A. $1.58\times 10^{-5}$
