HURRY PLEASE The density of tin is 7.3 g/cm3 and aluminum is 2.7 g/cm3. What is true about the density of a tin can that is coated with aluminum

1. Their is not enough information to determine the density of a can

2. The density is between 2.8 g/cm3 and 7.3 g/cm3

3. The density is 7.3g

4. The density is 2.7g/cm3

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.
