Answer:
Explanation:
2C₂H₂ + 5O₂ = 4CO₂ + 2H₂O .
CO₂ formed in moles = 33.4 / 44 = .76 moles
4 moles of CO₂ is formed by 2 moles of C₂H₂
.76 moles of CO₂ is formed by .38 moles of C₂H₂
.38 moles of C₂H₂ were present initially
2 moles of C₂H₂ produces 2 moles of water
.38 moles of C₂H₂ produces .38 moles of water
water produced = .38 moles
= .38 x 18 = 6.84 grams of water .
