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 %

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
