How many moles of hydrogen are in 3.0 moles of c6h12o6?

36 mol H

Explanation:

1 molecule C₆H₁₂O₆ contains 12 H atoms

1 mol C₆H₁₂O₆ contains 12 mol H atoms;      Multiply by 3

3 mol C₆H₁₂O₆ contains 36 mol H atoms

If you are talking about moles of hydrogen molecules (H₂), you divide 36 by 2 and get 18 mol H₂.
