Lab 1: Stoichiometry

NaHCO3 (aq) + CH3COOH (aq) ----> CO2 (g) + H2O (l) + CH3COONa (aq)

What is the molar ratio of NaHCO3 to CH3COONa?
What is the molar mass of each of the reactants and products?
How many moles of H2O will be produced from 2 moles of CH3COOH?
how many grams of CH3COOH?
How many grams of CO2 is produced from 3.2 grams of NaHCO3?

In this lab you will measure out the required amount and perform the combine the ingredients in a ziploc bag. You will measure the mass of the bag with the entire contents before and after the reaction.

Does your experiment abide by the law of convervation of mass? Why or why not?
