Calculate the pH for the following buffer solutions with steps.

1. 7.4862 grams of acetic acid and 10.4695 grams of sodium acetate are dissolved in enough deionized water to make 250.0 mL of solution.

2. 11.8115 grams of trimethylamine and 18.7088 grams of trimethylammonium chloride are dissolved in enough deionized water to make 500.0 mL of solution.

Thank You:)
