How many atoms are in this formula PCl6 ?

The molecule is unstable and impossible to create the PCl_6

Only one way is that change the formula

Lets look at structure(See attachment)

There are total 7atoms

the answer is 0.8m.

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.
