The purpose of this lab was to determine the mathematical relationship for yeast fermentation in the creation of mint ginger soda. The experiment was successful.
I predict the amount of gas produced over time by yeast is exponential, because it will keep growing overtime, and not by the same amount every single day.
1060 ml of dihydrogen monoxide, 120 ml of sucrose, One-Half package of yeast, Paper towel, Rubber band, 1000 ml beaker, Erlenmeyer Flask(250ml), Balloon(Non-latex), Metric measuring tape, Indirectly vented chemical-splash goggles.
Dissolve half a package of yeast in 60 ml of warm water
Use a graduated cylinder, measure 120ml of sucrose
Measure 150ml of sugar into a 250ml Erlenmeyer flask. Fill remainder with water.
Place balloon over top, place rubber band on the lip of balloon.
Use measuring tape to find circumference every day in class.
Copy into this packet.
Place flask in designated spot in classroom.

Was your initial hypothesis correct? Restate your hypothesis and identify whether you were correct or incorrect, using data to support your answer.
Yes, my hypothesis was correct (I predict the amount of gas produced over time by yeast is exponential, because it will keep growing overtime, and not by the same amount every single day.) My balloon did grow exponentially over time.
How large do you think if you measured the volume tomorrow? If I measured tomorrow I think it would be around 62 cm.
Based on the fermentation equation, if the amount of yeast is limitless, how many molecules of CO2 are created when yeast have 100 molecules of sucrose to break down? Explain how you arrived at your answer. You would need to have 298 molecules of CO2 to break down the yeast.
