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.
