Answer: 38.52 moles of hydrogen will be required to produce 19.26 mol of methane

Step-by-step explanation:

To calculate the moles :


\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}


\text{Moles of} CH_4=19.26moles

The balanced chemical reaction is:


C+2H_2\rightarrow CH_4

According to stoichiometry :

1 mole of
CH_4 is produced by = 2 moles of
H_2

Thus 19.26 moles of
CH_4 will be produced by =
(2)/(1)* 19.26=38.52moles of
H_2

Thus 38.52 moles of hydrogen will be required to produce 19.26 mol of methane
