Answer:
Yes the two of the answer is True
Your answer is going to be 200g
Answer:
93.28%
Explanation:
To solve the percent yield we need to find theoretical yield:
<em>Percent yield = Actual Yield (452.78g) / Theoretical yield * 100</em>
<em />
Theoretical yield is obtained converting the mass of acetylene to moles and using the balanced equation determine the moles of CO₂ produced assuming a 100% of reaction:
<em>Moles acetylene (Molar mass: 26.04g/mol)</em>
143.6g C₂H₂ * (1mol / 26.04g) = 5.515 moles C₂H₂
<em>Moles CO₂:</em>
5.515 moles C₂H₂ * (4 moles CO₂ / 2mol C₂H₂) = 11.029moles CO₂
<em>Mass CO₂ (Molar mass: 44.01g/mol):</em>
11.029moles CO₂ * (44.01g / mol) = 485.39g CO₂ is theoretical yield
Percent yield is:
Percent yield = 452.78g / 485.39g * 100
= 93.28%
