How many moles of methane (CH4) could be made from 4.6 moles of hydrogen?
DENIUS [597]

Number of moles of methane form = 2.3 mol

Explanation:

Given data:

Number of moles of Hydrogen = 4.6 mol

Number of moles of methane form = ?

Solution:

Chemical equation:

C + 2H₂     →   CH₄

Now we will compare the moles of methane with hydrogen from balance chemical equation.

                     H₂              :           CH₄

                       2              :             1

                     4.6             :            1/2×4.6 = 2.3 mol  

Form 3.6 moles of hydrogen 2.3 moles of methane can be formed.
