How many moles of hydrogen are in 3.0 moles of C6H12O6?

36 moles of Hydrogen

Solution:

The molecular formula of Glucose is,

C₆H₁₂O₆

As clear from molecular formula, each mole of Glucose contains 12 moles of Hydrogen atoms.

Therefore,

1 mole of C₆H₁₂O₆ contains = 12 moles of Hydrogen

So,

3.0 moles of C₆H₁₂O₆ will contain = X moles of Hydrogen

Solving for X,

X = (3.0 mol * 12 mol) : 1 mol

X = 36 moles of Hydrogen
