Question

How many grams of carbon dioxide would be produced if we use 35 grams of methane in the reaction below? CH4 +2O2---- Co2 + 2H2O

Answer 1

96g of CO₂ would be produced

Step-by-step explanation:

Based on the reaction:

CH₄ + 2O₂ → CO₂ + 2H₂O

1 moles of methane, CH₄ produces 1 mole of carbon dioxide, CO₂.

To solve this question we must find the moles of methane added in the reaction. These moles added are equal to moles of CO₂ produced. With the molar mass of CO₂ (44.01g/mol) we can find the grams that would be produced:

Moles CH₄ -Molar mass: 16.04g/mol-:

35g * (1mol / 16.04g) = 2.182 moles of CH₄ are added = Moles CO₂ produced.

Mass CO₂ produced.

2.182 moles CO₂ * (44.01g / mol) =

96g of CO₂ would be produced
