After leaving the cockroaches in their metabolic chamber for one hour, i measured the gases in the chamber. the fraction of oxygen in the chamber was 0.18. what was the metabolic rate of the cockroaches in ml o2/hr? (assume the room air is 21% o2 and chamber volume = 500ml.)

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

i think its 100.

hope this !
