To determine the mass of CO₂ produced, you need to know the amount (in moles) of sodium bicarbonate and citric acid used in the reaction. Without this information, you cannot calculate the exact mass. However, if you are given the mass of either sodium bicarbonate or citric acid, you can use their respective molar masses to calculate the number of moles, and then multiply by the molar mass of CO₂ to find the mass.
The balanced chemical equation for the reaction between sodium bicarbonate (NaHCO₃) and citric acid (C₆H₈O₇) is:
3NaHCO₃(aq) + C₆H₈O₇(aq) → 3CO₂(g) + 3H₂O(l) + Na₃C₆H₅O₇(aq)
From the equation, we can see that for every 3 moles of sodium bicarbonate and citric acid, 3 moles of carbon dioxide gas are produced. To determine the mass of carbon dioxide produced, we will need the molar mass of carbon dioxide (CO₂), which is approximately 44 g/mol.
