What is the hydrogen ion molarity of a solution with a pH of 10.16

The hydrogen ion molarity : 6.918 x 10⁻¹¹ M

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.  

pH = - log [H⁺]  

So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.  

A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.  

pH of solution = 10.16

the [H₃0⁺] of the solution :

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
