Students will anxiously watch the fruits of their labor to see if the bag fills up or pops open. These activities take students through exercises of determining the volume of a plastic bag, the molecular mass of the the two solids being reacted, the number of moles of gas needed to be produced to fill the volume of the bag, stoichiometry to determine the number of moles of reactants needed, and then determining the number of grams of reactants. Once the students determine the number of grams, the teacher or students can measure it out and try the experiment to see if the bag becomes fully inflated and does not pop open.
