of pieces that are 2/3 yard long that she can cut. Use the model to find the number of such pieces she can cut. How much ribbon will be left after she cuts these pieces?
PH can be calculated using the following equation pH = -log [H₃O⁺] for apple juice the hydronium /hydrogen ion concentration is 0.0003 pH = -log (0.0003) pH = 3.5 correct answer is C
For ammonia pH = -log (3.1 x 10⁻⁹) pH = 8.5 answer should be 8.5
