Hydrogen and oxygen react under a specific set of conditions to produce water according to the equation 2 H2(g) + O2(g) −→ 2 H2O(g). How much hydrogen would be required to produce 3 mol of water? Answer in units of mol.

The answer to your question is 3 moles

Explanation:

Data

moles of hydrogen = ?

moles of water = 3

Chemical reaction

                           2H₂  +  O₂   ⇒   2 H₂O

To answer this question we can use proportions and the coefficients of each molecule.

                 2 moles of Hydrogen 2 moles of water

                 x                                   3 moles of water

                 x = (3 x 2)/2

                 x = 6/2

                x = 3 moles of hydrogen

the ratio of the conjugate base to the acid required to attain the desired ph.
