You are asked to prepare 500. mL 0.300 M acetate buffer at pH 5.00 using only pure acetic acid (MW = 60.05 g/mol, pKa = 4.76), 3.00 M NaOH, and water. How many grams of acetic acid will be needed to prepare the 500. mL buffer? Note that the given concentration of acetate refers to the concentration of all acetate species in solution. mass: g What volume of 3.00 M NaOH, must be added to the acetic acid to achieve a buffer with a pH of 5.00 at a final volume of 500. mL? Ignore activity coefficients. volume: mL Pour the beaker contents into a 500 mL volumetric flask. Rinse the beaker several times and add the rinses to the flask. Swirl the flask to mix the solution. Add water to the mark to make the volume 500. mL. Stopper the flask and invert how many times to ensure complete mixing? O 1 O 2 20
