Piers & Aida performed this experiment. Aida read the initial volume of hydrogen peroxide as 7.5 mL, but Piers read the volume as 8.5 mL. Which of the following statement(s) are TRUE about Piers' calculations? I. Piers' calculations will give a higher value of moles of O(g) than Aida. II. Piers' calculations will give a higher partial pressure of O(g) than Aida. III. Piers' calculations will give a lower molarity of HO2 than Aida. Select one: I & II are true. II and III are true. I and III are true. Only III is true
