4. A buffer solution is prepared by dissolving 2.00 g each of benzoic acid, C6H5COOH (122.1 g/mol), and sodium benzoate, NaC6H5CO0 (144.1 g/mol), in 750.0 mL of water. Assume that the solution's volume is 750.0 mL. Ka of benzoic acid = 6.3 x 10-5 Calculate the molarity of C6H5COOH. Calculate the molarity of NaC6H5COO. Write the Henderson Hasselbalch equation for the above system with known values plugged in. Calculate the pH of this buffer.
