In an experiment reported in the scientific literature, male cockroaches were made to run at different speeds on a miniature treadmill while their oxygen consumption was measured. In one hour the average cockroach running at 0.08km/hr consumed 0.8 mL of O2 per gram of insect weight at 1 atm pressure and 24 °C. ▾ Part A How many moles of O2 would be consumed in 1 hr by a 5.1-g cockroach moving at this speed?
