Answer
Answer:
$1.78\times 10^{-4}\text{ M}$
Explanation:
Step1: Recall pH formula
The formula for pH is $pH = -\log[H^{+}]$.
Step2: Rearrange the formula
We can rewrite it as $[H^{+}]=10^{-pH}$.
Step3: Substitute the given pH value
Given $pH = 3.75$, then $[H^{+}]=10^{- 3.75}$.
Step4: Calculate the value
$10^{-3.75}\approx1.78\times 10^{-4}\text{ M}$.
