These questions require more thought and integrate several concepts.

You are given an acid and told only that it could be citric acid (molar mass = 192.1 g/mol) or tartaric acid (molar mass = 150.1 g/mol). To determine which acid you have, you react it with NaOH. The appropriate reactions are

You find that a 0.956-g sample requires 29.1 mL 0.513-M NaOH to reach the equivalence point. What is the unknown acid?
