Concept explainers
Interpretation: If one tablet containing 0.0119 moles of sodium hydrogen carbonate is dissolved, the moles of sodium citrate forms needs to be determined.
Concept Introduction: The mole concept provides the relation between moles, mass and molar mass. The mathematical expression of the mole concept can be written as:
1 mole of any substance contains
Answer to Problem 62A
Explanation of Solution
The reaction of sodium hydrogen carbonate with citric acid to form sodium citrate with carbon dioxide and water is as given below:
The mole ratio relates the moles of the reactant with other reactant and product molecules in a balanced chemical equation.
Moles of sodium hydrogen carbonate = 0.0119 moles
3 moles of sodium hydrogen carbonate = 1 mole of sodium citrate
Calculate moles of sodium citrate with the help of mole ratio:
Thus,
