This is the chemical formula for talc (the main ingredient in talcum powder): mg3(sios), (oh)2 an analytical chemist has determined by measurements that there are 22. moles of oxygen in a sample of talc. how many moles of hydrogen are in the sample? round your answer to 2 significant digits. 1 mol x 6 ?

3.67 moles of hydrogen are in the sample.

Explanation:

The chemical formula for talc =

In 1 mole of talc there are 12 moles of oxygen.

Then 22 moles of oxygen will be in:

of talc

In 1 mole of talc there are 2 moles of hydrogen.

Moles of hydrogen in 1.8333 moles of talc.

of hydrogen

3.67 moles of hydrogen are in the sample.

if you mean hydrogen and oxygen then water is the product

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.
