Question

What is the maximum amount in grams of CO2 produced when 6.00 grams of carbon combines with oxygen gas?

Answer 1

*The maximum amount may depend on the source of Carbon you use. For example i will use methane as the source of Carbon:

CH₄ + 2O₂ CO₂ + 2H₂O

According to the balanced equation : 2O₂ 1CO₂

which means : 1O₂ 1/2 CO₂

1 mole O₂ will give 1/2 mole CO₂

Say 100 g of O₂ was used.

Number of moles of O₂ = Mass / Molar mass

= 100 g /31.9988 g = 3.125 moles

3.13 moles will give 1/2 * 3.125 moles CO₂ = 1.56 moles CO₂

1.56 moles CO₂ = 1.56 mole * 44.0098 g/mole = 68.78 g CO₂
