How many moles of hydrogen are in 3.0 moles of C6H12O6?
tangare [24]
<h3>Answer:</h3>

              36 moles of Hydrogen

<h3>Solution:</h3>

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
