Question
Now, let's use what we know about chemistry to infer how much acetic acid was in our sample. Let's
look closely at the equation for the reaction we performed.
HC2H3O2(aq) + NaHCO3(s) → NaC2H3O2(aq) + H2O(1) + CO2(g)
Based on this balanced chemical reaction, we can see that for every one mole of CO2 that was
produced one mole of acetic acid was consumed. Based on this, calculate the moles of acetic acid
and grams of acetic acid that must have reacted in each sample.
