Question

For the reaction C + 2H2 - CH2, how many moles of hydrogen are required to produce
19.26 mol of methane, CHA?
Select one:
O a. 19.26
O b. 38.52
O c. 15.0
O d. 24.7

Answer 1

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

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 =$\frac{2}{1}\times 19.26=38.52moles$  of $H_2$

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

Answer 2

the answer is 38.52 moles of hydrogen
