Question

In the following reaction, how many grams of carbon dioxide will be produced by 100 grams of ethylene (C2H4)? Click the equation below to go to the Equation Balancer tool and balance it. Then use it for your calculation. The molar mass of ethylene is 28.0516 grams and that of carbon dioxide is 44.01 grams.

Answer 1

Ethene on combustion reaction produces CO₂ and H₂O,

C₂H₄ + 3 O₂ → 2 CO₂ + 2 H₂O

According to Equation,

28.05 g (1mole) C₂H₄ produced = 88 g (2 mole) of CO₂
So,
100 g of C₂H₄ will produce = X g of CO₂

Solving for X,

X = (100 g × 88 g) ÷ 28.05 g

X = 313. 72 g of CO₂
