Answer:

The answer to your question is 92.23 g of CO₂

Step-by-step explanation:

2C₂H₂ + 5O₂ ⇒ 4CO₂ + 2H₂O

Process

1.- Calculate the molecular mass of C₂H₂ and CO₂

Molecular mass C₂H₂ = (12 x 2) + (1 x 2) = 24 + 2 = 26 g

Molecular mass CO₂ = (12 x 1) + (16 x 2) = 12 + 32 = 44g

2.- The balance reaction and proportion to find the amount of CO₂ produced.

2(26) g of C₂H₂ --------------- 4(44) g of CO₂

54.5 g of C₂H₂ --------------- x

x = (54.5 x 88) / 52

x = 92.23 g of CO₂
