Question

CH4(g) + 2O2(g) = CO2(g) + 2H2O(g)

How many moles of CH4 are required to react completely with 0.08 mole of O2?

Answer 1

0.04 moles of CH₄ are required

Step-by-step explanation:

Given data:

Number of moles of CH₄ required = ?

Number of moles of O₂ present = 0.08 mol

Solution:

Chemical equation:

CH₄ + 2O₂ → CO₂ + 2H₂O

now we will compare the moles of oxygen and methane.

O₂ : CH₄

2 : 1

0.08 : 1/2×0.08 = 0.04

Thus, 0.04 moles of CH₄ are required.
