The volume is 500 mL, the mass of air is 60g (molar mass of air= 29g/mol), and the temperature is 600 C, what is the pressure inside the bottle?

How to calculate molar mass of a gas? 1 Pressure = Atmosphere (atm) 2 Volume = Liters (L) 3 Temperature = Kelvin (K) The molar mass equation Molar mass = Mass / Moles.

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.
