WebCalculating pH. To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter . The pH is then calculated using the expression: pH = - log [H 3 O +]. Example: Find the pH of a 0.0025 M HCl solution. The HCl is a strong acid and is 100% ionized in water. WebIn the Philippines, some universities follow a 4-Point Scale, which resembles or is equivalent to the U.S. grading system. This system uses a grade between 0.00 to 4.00 wherein 4.00 is the highest and 0.00 being a failing mark. Other universities follow a 5-Point Scale, wherein the highest grade is a 1.00 and the lowest is a 5.00 (failing mark).
