Question

When an antacid tablet dissolves in water, the fizz is due to a reaction between sodium hydrogen carbonate (sodium bicarbonate, NaHCO₃) and citric acid (H₃C₆H₅O₇).

3 NaHCO₃(aq) + H₃C₆H₅O₇(aq)  3 CO₂(g) + 3 H₂O(l) + Na₃C₆H₅O₇(aq)

How many moles of Na₃C₆H₅O₇ can be produced if one tablet containing 0.0319 mol of NaHCO₃ is dissolved?

Answer 1

0.0319 mol of NaHCO₃ x 1 mol Na₃C₆H₅O₇/mol NaHCO₃ = answer
