A sample of 0.05567 mole sodium acetate was dissolved into 150.0 mL of water. If 2.00g of NaOH(s) was added to the solution and allowed to dissolve, what is the pH of this new solution? Assume no volume change after NaOH(s) was added. Molar Mass NaOH= 39.998 g/mol. Answer given was pH = 13.52, What are the steps to get here?
