You determine the ph of an energy drink is 4.33. what is the hydronium ion concentration, [h3o+]?

First, we must know that the hydronium ion is formed when a water molecule accepts a hydrogen ion. Therefore, the hydronium ion concentration is equivalent to the hydrogen ion concentration. Furthermore, the equation relating pH and hydrogen ion concentration is:

pH = -log[H+]

4.33 = -log[H+]
[H+] = 4.68 x 10⁻⁵ M

The concentration of hydronium ions is 4.68 x 10⁻⁵ M

True, the standard unit for volume is liters which can be represented by either a lower case "l" or a capital "l"

Sorry i dont understand the question can you rephase it?
