Question

2H20--12H2 + O2
How many moles of H2 are produced when 2.54 moles of H2O reacted?

Answer 1

Answer:

2.54mole of H₂

Explanation:

The reaction expression is given as:

           2H₂O  →   2H₂  +   O₂

Given;

Number of moles of H₂O  = 2.54moles

Unknown:

Number of moles of H₂ produced  = ?

Solution:

To solve this problem, we use the concept of mole comparison. Now from the reaction expression, we know that;

                  2 mole of H₂O will produce 2 mole of H₂

                 2.54 mole of H₂O will then produce 2.54mole of H₂
