Chemical equation of the reaction between citric acid and baking soda:
[tex] C_{6} H_{8} O_{7} +3NaHCO_{3} -\ \textgreater \ Na_{3} C_{6} H_{5} O_{7} +3 H_{2} O+3CO_{2} [/tex]
Ratios
Citric Acid Baking soda -> Sodium Citrate Water Carbon Dioxide
C6H8O7 CO2
1 mole 3moles
Molecular masses
Citric acid
6*12 + 8*1 + 7*16 = 192 g/mole
Carbon dioxide
12 + 2*16 = 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.
