To find the theoretical yield of carbon dioxide, we need to follow these steps:1. Calculate the molar mass of citric acid (H3C6H5O7) and baking soda (NaHCO3).2. Convert the mass of citric acid to moles using its molar mass.3. Use the stoichiometry of the balanced chemical equation to determine the moles of carbon dioxide produced.4. Convert the moles of carbon dioxide to grams using its molar mass.Let's go through these steps:1. Molar masses: - Citric acid (H3C6H5O7): 192.12 g/mol - Baking soda (NaHCO3): 84.01 g/mol - Carbon dioxide (CO2): 44.01 g/mol2. Convert the mass of citric acid to moles: Moles of citric acid = 1300 g / 192.12 g/mol = 6.75 mol3. Use the stoichiometry of the balanced equation: According to the balanced equation, 1 mole of citric acid produces 3 moles of carbon dioxide. Moles of carbon dioxide = 6.75 mol * 3 = 20.25 mol4. Convert the moles of carbon dioxide to grams: Theoretical yield of carbon dioxide = 20.25 mol * 44.01 g/mol = 893.9 gTherefore, the theoretical yield of carbon dioxide is 893.9 g.
