11. Pour the yeast into the empty 30-mL bottle. 12. Measure 1 mL of hydrogen peroxide in the 10-mL graduated cylinder. Record the exact volume in Data Table 1. 13. Prepare the end of the tubing with the dropper top. 14. Pour the hydrogen peroxide into the 30-mL bottle. 15. Snap the dropper top with tubing onto the bottle. 16. Allow the reaction to proceed until no additional gas has been generated for at least one minute. At this point, the reaction can be considered complete. 17. Record the final volume of gas in Data Table 1.
18. Calculate the change in volume in mL and record in Data Table 1. 19. Remove the top from the bottle, pour the contents down the sink, and rinse the bottle three times with water. 20. Repeat the activity using 1 mL hydrogen peroxide. 21. Repeat the activity varying the volume of hydrogen peroxide in step 12 as listed in the table below. Activity 2 - 1. Calculate the molarity of (mol/L) of 3% hydrogen peroxide and record it in Data Table 2. The term “3% concentration” is a weight-to-weight measurement, which means that there are 3 g solute per 100 g solvent. 2. Calculate the moles of hydrogen peroxide present in each trial. 3. Calculate the moles of oxygen generated in each trial. 4. Convert the change in volume from Activity 1 to liters. 5. Convert the air temperature from Activity 1 from Celsius to Kelvin. 6. Using a computer graphing program, create an XY scatter plot of the moles of oxygen vs. volume of gas generated. 7. Create a best-fit line on your graph. Set the y-intercept equal to zero and display
