How many moles of methane are produced when 82.6 moles of carbon dioxide gas react with excess hydrogen gas?

82.6 moles

Explanation:

chemical equation:

CO2+ 4H2  → CH4 + 2H2O

Given data:

moles of carbon dioxide = 82.6 mol

moles of methane = ?

through the balanced chemical equation we will compare the moles carbon dioxide with methane

   CO2  :  CH4

     1      :     1

   82.6  :    82.6

we are given hydrogen so 82.6 moles of carbon dioxide will produce 82.6 moles of methane.
