Answer 1

10 mol of H₂ required to produce 5 moles of methane (CH₄)  

What is Mole ratio ?

Mole Ratio is a conversion factor between compounds in a chemical reaction, that is derived from the coefficients of the compounds in a balanced equation.

The mole ratio is therefore used to convert between quantities of compounds in a chemical reaction.

Given reaction ;

                                                  C + 2H₂ -------> CH₄  

from reaction                              2 mol           1 mol

from the question                      x mol           5 mol                       (given)

Now,

x = 2 x 15 / 1 = 10 mol

                     = 10 mol of H₂.

Hence, 10 mol of H₂ required to produce 5 moles of methane (CH₄)
