Calculate the amount of vinegar (CH3COOH) needed to react completely with 1 gram of baking soda (NaHCO3). Now (with the false assumption that vinegar is 100% acetic acid and the good assumption that vinegar has the same density as water (1g/mL)) calculate the amount of vinegar needed to react completely with the amount of NaHCO3in one of the ~1 gram containers.
