Answer:
46.97g
Explanation:
Hello,
To find the theoretical yield, we must first of all get the equation of reaction right in order to know how the compounds combine together.
Equation of reaction;
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
From the equation of reaction,
2 moles of C₂H₆ reacts with 7 moles of O₂ to produce 4 moles of CO₂.
Number of moles = mass / molar mass
Mass = number of moles × molar mass
Mass of CO₂ = 4 × 44 = 176g
Mass of C₂H₆ = 2 × 30 = 60g
Mass of O₂ = 7 × 32 = 224g
Therefore, 224g + 60g (O₂ + C₂H₆) = 176g of CO₂.
284g of reactants = 176g of product(COâ‚‚)
(18 + 57.8)g of reactants = x g of products(COâ‚‚)
X = (75.8 × 176) /284
X = 46.97g of COâ‚‚.
Theoretical yield of COâ‚‚ is 46.97g
