an oxygen tank used for scuba diving has. avolume of 12.0 L .If the pressure of the tank is known to be 204.047 atm and the temperature is 22.0 C(295 K), how many moles of oxygen are contained in the tank

101 moles of oxygen are contained in the tank

Explanation:

According to ideal gas equation:

P = pressure of gas = 204.047  atm

V = Volume of gas = 12.0 L

n = number of moles  = ?

R = gas constant =

T =temperature =

Thus 101 moles of oxygen are contained in the tank

b i think it’s a water wheel turning in a stream

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
