Answer:
3.67 moles of hydrogen are in the sample.
Explanation:
The chemical formula for talc =[tex] Mg_3(Si_2O_5)_2.(OH)_2[/tex]
In 1 mole of talc there are 12 moles of oxygen.
Then 22 moles of oxygen will be in:
[tex]\frac{1}{12}\times 22=1.8333 mol[/tex] of talc
In 1 mole of talc there are 2 moles of hydrogen.
Moles of hydrogen in 1.8333 moles of talc.
[tex]=1.8333\times 2 mol=3.6666 mol\approx 3.67 mol[/tex] of hydrogen
3.67 moles of hydrogen are in the sample.
