WebAug 14, 2024 · Because only 4.98 mmol of OH − has been added, the amount of excess H + is 5.00 mmol − 4.98 mmol = 0.02 mmol of H +. B The final volume of the solution is 50.00 mL + 24.90 mL = 74.90 mL, so the final concentration of H + is as follows: [H +] = 0.02 mmol H + 74.90mL = 3 × 10 − 4 M Hence, pH ≈ − log[H +] = − log(3 × 10 − 4) = 3.5 WebTo find the percent composition (by mass) for each element in C2H4O2 we need to determine the molar mass for each element and for the entire C2H4O2 compound....
