Titration problem?? A 10.0-mL sample of pineapple juice was titrated with 0.100 M sodium hydroxide solution. The average volume of NaOH required to reach the endpoint was 12.8 mL. *Using the mole ratio for the neutralization reaction, determine the number of moles of citric acid in 10.0 mL of pineapple juice. *Multiply the number of moles of citric acid by its molar mass to calculate the mass of citric acid in 10.0 mL of the juice. *The concentration of acid in juices is usually expresses in grams of acid per 100 mL of juice. What is the concentration of citric acid in pineapple juice?
