Question

For the reaction #CH_4 + 2O_2 -> CO_2 + H_2O#, how many moles of carbon dioxide are produced from the combustion of 100g of methane?

Natalie Anton · Accepted Answer

The moles of carbon dioxide produced from 100 g methane is 6 moles.

Balanced Equation #"CH"_4 + "2O"_2"##rarr##"CO"_2 + "2H"_2"O"# First, the given mass of methane must be converted to moles. For this you need the molar mass. The molar mass of #"CH"_4# is #"16.043 g/mol"#. https://tutor.hix.ai Multiply the given mass by the inverse of its molar mass. #100color(red)cancel(color(black)("g CH"_4))xx(1"mol CH"_4)/(16.043color(red)cancel(color(black)("g CH"_4)))="6 mol CH"_4# (rounded to one sig fig based on 100 g) Now multiply the moles methane by the mole ratio between methane and carbon dioxide so that methane is canceled. #6color(red)cancel(color(black)("mol CH"_4))xx(1"mol CO"_2)/(1color(red)cancel(color(black)("mol CH"_4)))="6 mol CO"_2# (rounded to one sig fig based on 100 g)

undefined 1 mole of CH₄ produces 1 mole of CO₂. Therefore, 100g of CH₄ produces approximately 220g (mol. wt. of CO₂ = 44 g/mol) of CO₂.
