Problem: 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 0.08 km/hr consumed 0.8 mL of O2 per gram of insect weight at 1 atm pressure and 24 oC.How many moles of O2 would be consumed in 1 hr by a 5.3 -g cockroach moving at this speed?

🤓 Based on our data, we think this question is relevant for Professor Kajstura's class at VALENCIA.

Concept: Ideal Gas Law.

Notice how we can first solve for the volume of O2 consumed in an hour time.

Next we will use the Ideal gas Law to solve for moles of O2, given Temperature and Pressure.
