To prepare a 19.7 kg dog (assume volume of 19.7 L) for surgery, 0.0273 moles of an anesthetic was administered intravenously. The reaction in which the anesthetic is metabolized displayed a first half life of 80.48 minutes and a second half life of 40.24 minutes. After 24.95 minutes of surgery the drug began to lose its effect, but more surgery was required. How many moles of the anesthetic must be re-administered to restore the original level of the anesthetic

consider the reaction below.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
