Answer the following questions on a separate piece of paper and upload a file with an image of
your answers.
(a) Assuming that the volume of the balloon is equal to the volume of carbon dioxide gas
produced in the reaction, calculate the number of moles of carbon dioxide produced.
(b) Calculate the molar mass of glucose.
(c) Did all the glucose react during the experiment? Justify your answer with a calculation and
an explanation.
(d) If the student's estimate of the balloon's volume was incorrect and the actual volume was
620 mL, would the amount of glucose that actually reacted be more than or less than the
amount calculated in part (c)? Explain your response.

5. A student conducts a laboratory investigation of anaeroblo respiration. The student places 10.0 g of glucose in a yeast solution in
a small flask with an uninflated balloon oer the top of the flask as shown below. The experiment is conducted at a temperature of
45°C and a pressure of 1.0 atm. After 10 minutes, the student estimates the volume of the balloon to be 550 mL.
V= 550
