A student performed the experiment described in this module, using 6.00 mL of a 3% H2O2 solution witha density of 1.03 g mL-1. The water temperature was 22 C, and the barometric pressure in the laboratory w 30.30 in. Hg. After the student immersed the yeast in the peroxide solution, she collected 65.40 mL of O2 (9) Calculate the number of moles of collected O

Answers

Volume of Oq collected, v= 65.40 mL = 0.06540L T= 22°C = (22+273-15) K = 295.15k p= 30.30 in Hg = 30.30 in Hg x/2.54cm g et TComment in case of any doubt.
