Answer:
Explanation:
CH₄ + 2O₂ = CO₂ + 2H₂O
C₂H₄ + 3O₂ = 2CO₂ + 2H₂O
Let volume of CH₄ be V , so volume of C₂H₄ will be 5 - V
CH₄ + 2O₂ = CO₂ + 2H₂O
1 vol 2 vol
V 2 V
V vol of CH₄ will require 2 V of O₂
C₂H₄ + 3O₂ = 2CO₂ + 2H₂O
5 - V 3( 5 - V )
5 - V vol of C₂H₄ will require 3 ( 5 - V ) vol of oxygen .
Total oxygen required = 2 V + 3 ( 5 - V )
2 V + 3 ( 5 - V ) = 13.2
2 V + 15 - 3V = 13.2
V = 1.8 ml
vol of CH₄ = 1.8
vol of C₂H₄ = 5 - 1.8 = 3.2 ml.
