Interpretation Introduction

Interpretation: The molarity of citric acid $\left({\text{C}}_{\text{6}}{\text{H}}_{\text{8}}{\text{O}}_{\text{7}}\right)$ in commercially available lemon juice and the amount of citric acid in $100.0\text{mL}$ of the juice are to be calculated.

Concept introduction: The concentration of a solution is defined as the number of moles of solute dissolved in a liter of solution. Concentration of a solution is expressed in moles per unit volume of a substance.

To determine: The molarity of citric acid $\left({\text{C}}_{\text{6}}{\text{H}}_{\text{8}}{\text{O}}_{\text{7}}\right)$ and the amount of citric acid in $100.0\text{mL}$ of the juice.
