Calculate the change in volume in mL and record in Data Table 1.
Remove the top from the bottle, pour the contents down the sink, and rinse the
bottle three times with water.
Repeat the activity using 1 mL hydrogen peroxide.
Repeat the activity varying the volume of hydrogen peroxide in step 12 as listed
in the table below.
Activity 2 -
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.
Calculate the moles of hydrogen peroxide present in each trial.
Calculate the moles of oxygen generated in each trial.
Convert the change in volume from Activity 1 to liters.
Convert the air temperature from Activity 1 from Celsius to Kelvin.
Using a computer graphing program, create an XY scatter plot of the moles of
oxygen vs. volume of gas generated.
Create a best-fit line on your graph. Set the y-intercept equal to zero and display
