Answer:

C) 4

Explanation:

The reaction :

  • C (s) + 2H₂ (g) ⇒ CH₄ (g)

       12g      4g             16g

Hence, based on this we can say that : 2 moles of hydrogen gas are needed to produce 16g of methane.

For 32g of methane

  • Number of moles of H₂ = 32/16 × 2
  • Number of moles of H₂ = 4

Moles of methane

  • Given mass/Molar Mass
  • 32/16
  • 2mol

2moles hydrogen required for 1 mol CH_4 production

For 2 mol CH_4

Moles of H_2=2(2)=4
