Answer:

Im pretty sure its B

Explanation:

Neetoo

Answer:

G) 50 mol

Explanation:

Given data:

Mass of methane = 800 g

Number of moles of CO₂ produced = ?

Solution:

Chemical equation:

CH₄ + 2O₂      →      CO₂ + 2H₂O

Number of moles of methane:

Number of moles = mass/molar mass

Number of moles = 800 g/ 16 g/mol

Number of moles = 50 mol

Now we will compare the moles of methane and carbon dioxide.

                 CH₄        :         CO₂

                    1           :          1

                  50          :        50
