Answer 2

Calculating Percentage Yield of Aniline Production

To calculate the percentage yield of aniline production, we can use the formula:

Percentage Yield = (Actual Yield / Theoretical Yield) x 100%

Given: - Actual Yield of Aniline = 150 g - Theoretical Yield of Aniline = ? - Nitrobenzene used = 250 g

We need to find the theoretical yield of aniline to calculate the percentage yield.

Calculating Theoretical Yield of Aniline

The molar ratio of nitrobenzene to aniline in the reaction is 1:1. This means that 1 mole of nitrobenzene should theoretically produce 1 mole of aniline.

Using the molar mass of nitrobenzene (C6H5NO2) and aniline (C6H5NH2): - Molar mass of nitrobenzene = 123.11 g/mol - Molar mass of aniline = 93.13 g/mol

We can use the molar ratio and the given mass of nitrobenzene to calculate the theoretical yield of aniline.

Theoretical Yield of Aniline = (Mass of Nitrobenzene used / Molar mass of Nitrobenzene) x Molar mass of Aniline

Theoretical Yield of Aniline = (250 g / 123.11 g/mol) x 93.13 g/mol

Theoretical Yield of Aniline = 190.89 g

Calculating Percentage Yield

Now that we have the actual yield and theoretical yield of aniline, we can calculate the percentage yield using the formula:

Percentage Yield = (Actual Yield / Theoretical Yield) x 100%

Percentage Yield = (150 g / 190.89 g) x 100%

Percentage Yield ≈ 78.6%

So, the percentage yield of aniline production is approximately 78.6% compared to the theoretical yield.
