Toulene, c6h5ch3 is oxidized by air under carefully controlled conditions to benzoic acid, c6h5co2h, which is used to prepare the food perservative sodium benzoate, c6h5co2na. what is the percent yield os a reaction that converts 1000 kg of toulene to 1.21 kg of benzoic acid
2c6 h5 ch3 + 3o2 ? 2c6 h5 co2 h + 2h2o

Answer : The percent yield of the reaction is, 0.0913 %

Explanation : Given,

Mass of = 1000 kg  = 1000000 g

Molar mass of = 98.14 g/mole

Molar mass of = 122.12 g/mole

First we have to calculate the moles of .

Now we have to calculate the moles of .

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 2 moles of react to give 2 moles of

So, 10853.05 moles of react to give 10853.05 moles of

Now we have to calculate the mass of .

Theoretical yield of = 1325374.466 g

Actual yield of = 1.21 kg = 1210 g

Now we have to calculate the percent yield of

Therefore, the percent yield of the reaction is, 0.0913 %
