Answer:

The concentration of hydrogen ions in moles per liter (M) is $3.981 * 10^{-9}$

Step-by-step explanation:

As we know

The hydrogen ion concentration of any solution at pH is given by

$H^+ = 10^{-pH}$

Substituting the given values in above equation, we get -

$H^+ = 10^{-8.4}\\H^+ = 3.981 * 10^{-9}$ mol/l

The concentration of hydrogen ions in moles per liter (M) is $3.981 * 10^{-9}$
