The final volume of buffer solution must be 100.00 mL and the final concentration of the weak acid must be 0.100 M. Based on this information, what mass of solid conjugate base should the student weigh out to make the buffer solution with a pH of 3.00? mass = g Based on this information, what volume of acid should the student measure to make the buffer solution? volume = mL
