Question
A student performed the experiment described in this module, using 5.00 mL of a 2.50% H2O2 solution with a density of 1.01 g mL. The water temperature was 24 ° C, and the barometric pressure in the laboratory was 30.50 in. Hg. After the student immersed the yeast in the peroxide solution, she collected 43.70 mL of O,. (3) Calculate the pressure, in torr, exerted by the collected O, at the water temperature.

Expert Solution
Step 1

According to the question,

we have: 5.00 ml of a 2.50% H2O2 solution 

Density of H2O2 solution = 1.01 g/ml

Water temperature = 24 degree celsius

Barometric pressure = 30.50 in Hg

Volume of O2 = 43.70 ml.

We need to calculate the pressure in torr, exerted by the collected O2 at the water temperature.
