Pembahasan:

Mr O₂ = 2 × Ar O
Mr O₂ = 2 × 16
Mr O₂ = 32

m O₂ = n O₂ × Ar O₂
m O₂ = 2 mol × 32
m O₂ = 64 gram

(anggap massa keduanya sama)

Mr CO₂ = 1 × Ar C + 2 × Ar O
Mr CO₂ = 1 × 12 + 2 × 16
Mr CO₂ = 12 + 32
Mr CO₂ = 44

n CO₂ = m CO₂ / Ar CO₂
n CO₂ = 64 gram / 44
n CO₂ = 1,454 mol

V CO₂ : V O₂ = n CO₂ : n O₂
V CO₂ : 100 ml = 1,454 mol : 2 mol
V CO₂ = 1,454 mol / 2 mol × 100 ml
V CO₂ = 72,73 ml
