1. Is it important to ensure the graduated cylinder is completely devoid of gas before starting a
trial? Why or why not?
2. Would the volume of oxygen that is generated be affected if a smaller mass of yeast were
3. Identify some potential sources for the error in the experiment. Are any assumptions made
that would add to the experimental error?
4. You are designing an experiment to measure pressure change with respect to moles of gas.
Propose a potential experimental design for a system in which the volume is constant. Assume
you have a method for measuring pressure. T
