What mass of co2 is produced by the combustion of 1.00 mol of ch4?

The balanced equation for the combustion of CH₄ is as follows

CH₄ + 2O₂ - - - > CO₂ + 2H₂O

stoichiometry of CH₄ to CO₂ is 1:1

therefore molar ratio of CH₄ to CO₂ is 1:1

the number of CH₄ moles combusted - 1.00 mol

number of CO₂ moles formed = number of CH₄ moles reacted

therefore number of CO₂ mol formed - 1.00 mol

mass of CO₂ produced - 1.00 mol x 44 g/mol = 44.0 g

mass of CO₂ produced is 44.0 g
