Chemical equation of the reaction between citric acid and baking soda:
\(C_{6} H_{8} O_{7} +3NaHCO_{3} -\ \textgreater \ Na_{3} C_{6} H_{5} O_{7} +3 H_{2} O+3CO_{2}\)
Ratios
Citric Acid Baking soda -> Sodium Citrate Water Carbon Dioxide

1 mole 3moles
Molecular masses
Citric acid
612 + 81 + 716 = 192 g/mole
Carbon dioxide
12 + 216 = 44 g/mole
Proportion carbon dioxide / citric acid
3 44 g of carbon dioxide / 192 g of citric acid
132 g of carbon dioxide / 192 g of citric acid
13.00 g of citric acid [132 g of carbon dioxide / 192 g of citric acid] = 8.94 g of carbon dioxide.
Answer: 8.94 grams.
