So we're given with the falling reaction off. See, six at six, along with bro. Mean, we need to calculate the moves off benzene that is being form the mole off benzene. We know the formula for number off mole is weight divided by more legal. A mass. The molecular mass off benzene is 78 by the mass. Provided is 30 grams. So the more stones out doobie 0.384 more. Same has to be done for broom in b r. Two weight divided by molecular mass. So the way it provided in Broome mean cases 65 by the molecule amasses 159.8. You can round it up. 260. No limiting the agent limiting reactant is the reactant which gets totally consumed in a complete chemical reaction. On it is the reactor that determines the amount off product formed. We can data mine the limiting the agent for the falling above reaction as follows. So one mole off Benzene. Yes. One more off. Benzene reacting with one more off blue mean to form one mole off, bro Mo Benzie. Hence one more off benzene forms one more off, bro. Mo Benzene. We can write it over here. One benzene gives us one broom. Oh, Benzine. Then 0.384 moles off. Benzene will provide 0.3 years. Moles off, bro. Mo Benzie along with that one more off, bro. Mean one more log off, bro. Mean provides us one more log off, bro. Mo Benzene. So 0.407 Moles off, bro. Me will give us 0.407 Moles off, bro. Move Benji for the same case. One more off, bro. Mo Benzene More law for benzene form is less than the mole off roaming, which differs. Benzene consumes first in the reaction hens. Benzene will act as a limiting the agent. Or you can simply deter mined that which off the reactor has lesson number off moves will be acting as the limiting the agent in this case, benzene. For though benzene is the limiting the actor and brew mean is the XX reacted? The more visual between benzene and Bruno Benzene is one racial one. So the mole off, bro Mo benzene are equal to the mall off benzene. That zero point 384 more the mask off, bro. Move. Benzene. His 157 grams. We need to calculate the mass off, bro. Move Benzene as morals off, bro Mo Benzie multiplied with the molar mass off bro mo Benzene, which gives us the mask off bro. Movements in produced, that is 60.3 grams for the the actually yield ISS actually yield is 42 point three grams, while theoretical is 60 point three grams. We need to calculate the percentage deal as follow. So person you formula is actually divided by theoretical multiplied with 100 which gives us for the 2.3 divided by 60.3 multiplied with 100 give this 70.1% off field.
