In this question, we need to calculate the molarity or the molar concentration of [H+] in a solution that has pOH = 5.33
First, we need to find the pH of this solution, and pH and pOH have a relationship that both values must equal 14:
pH + pOH = 14
pH = 14 - 5.33
pH = 8.67
Now that we have the value of pH, we can find the molar concentration of [H+], using the following formula:
[H+] = 10^-pH
[H+] = 10^-8.67
[H+] = 2.14*10^-9 of molarity or molar concentration
