help me to solve this problem from the graph given below (Amino acid titration )

Amino Acid Titration Identify the first equivalence point on the titration curve. (1pts) What is the volume ( mL ) needed to reach the first equivalence point? (1pts) Volume (mL) at 50% of the first equivalence point. (1pts) Estimate the pH at 50% volume of the first equivalence point. (2pts) What is pKa1 ? Identify the second equivalence point on the titration curve. (1pts) What is the volume (mL) needed to reach the second equivalence point? (1pts) Volume ( mL) at 50% between the first and second equivalence point. (1pts) Estimate the pH at the volume 50% between the first and second equivalence point. (2pts) What is pKa2
