If you have 2 grams of acetic acid and 2 grams of sodium bicarbonate do you have the same number of molecules of each compound?

No you do not. The gram-formula mass of sodium bicarbonate is 74, while the mass of acetic acid is 60. If the mass is both 2 grams, the proportion does not work.
(2gNaHCo3/74gNaHCo3) = (2gCH3COOH/60gCH3COOH) is a false statement. One could also use dimensional analysis, but because there were very little conversions, I felt that proportions were easier.
