g. The two substances react, releasing carbon dioxide gas to the atmosphere. After the reaction, the contents of the reaction vessel weigh 11.9
g. What is the mass of carbon dioxide released during the reaction
Expert's answer
NaHCO3 + CH3COOH = CH3COONa + ^CO2 + H2O
3.3 + 10.7 = 14 g total mass.
14 - 11.9 = 2.1 g mass of CO2.
