A 13.00 g sample of citric acid reacts with an excess of baking soda as shown in the equation.
H3C6H507 +3NaHCO3 →3CO2 + 3H₂O+Na3C6H507
What is the theoretical yield of carbon dioxide?
0.993 g
O2.98 g
O 3.65 g
8.93 g
From Law of definite proportion You can compare this Citric acid (Mw) / 3CO2 (Mw) = Citric acid (g) / 3CO2 (g) So (12)6+(1)8+(16)7 / 3[12 + (16)2] = 13 / 3CO2 192 / 132 = 13 / CO2 You can get 3CO2 = 8.93 g
