Question

Use the following experimental data to calculate the following 4 questions:

Initial amount of the mixture = 1g Ferrocene + 1g Acetyl Ferrocene.

Initial weight of flask 1= 20.525g

Final weight flask 1+Ferrocene recovered = 21.235g

Initial weight of flask 2 = 20.235g

Final weight of flask 2+Acetyl ferrocene recovered = 20.925g

Answer 1

1)

Mass of the recovered ferrocene = 21.235 – 20.525

Mass of the recovered ferrocene = 0.71 gram

Option A is correct.

2)

Mass of the recovered acetyl ferrocene = 20.925 – 20.235

Mass of the recovered acetyl ferrocene = 0.69 gram

Option C is correct.

3)

Percent yield of ferrocene = 0.71*100/1

Percent yield of ferrocene =71%

Option B is correct.

4)

Percent yield of acetyl ferrocene = 0.691*100/1

Percent yield of acetyl ferrocene =69.1%

Option C is correct.
