how many moles of hydrogen are there in 2 moles of c2h6?
158845
Notice how the "moles of C2H6" can cancel, giving you your answer: 12 moles of hydrogen.
164673
This also means that in one mole of iso-octane, there are 8 moles of carbon and 18 moles of hydrogen. The empirical formula is the simplest whole-number ratio of atoms in the compound. For iso-octane, the empirical formula is C4H9.

Each methane (CH4) molecule has 4 hydrogen atoms. 1 mole of anything has 6.022 X 10^23 molecules (Avagadro's number).
824748
Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms. Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water.
