There are 2.43 x 1026 molecules of water in the Pacific Ocean. How many moles of water is this?

Thus there are 404 moles of water in this.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

To calculate the moles, we use the equation:

Thus there are 404 moles of water in this.

Explanation:

The number of moles is given by dividing the total number of molecule of water by the Avogradro's Number:

56 moles of   lieter in chemistry

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.
