2C10H11NO4 + 2H2O → C16H10N2O2 + 2C2H4O2 + 4H2O

In this reaction, 1.87 g of indigo (C16H10N2O2) are produced.

If the theoretical yield is 2.35 g of C16H10N2O2, what is the percent yield of indigo?

Round to the nearest decimal.

Answer 1

The percent yield of indigo : 79.6%

Further explanation

Percent yield is the comparison of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

2C₁₀H₁₁NO₄ + 2H₂O → C₁₆H₁₀N₂O₂ + 2C₂H₄O₂ + 4H₂O

Actual yield = 1.87 g

Theoretical yield = 2.35 g

The percent yield of indigo :

$\tt \%yield=\dfrac{actual}{theoretical}\times 100\%\\\\\%yield=\dfrac{1.87}{2.35}\times 100\%=\boxed{\bold{79.6\%}}$
