Anthroquinone (C14H8O2), an important intermediate in the dye industry, is produced from the reaction of benzene with phthalic anhydride (C8H4O3), followed by dehydration with sulfuric acid. The overall reaction is...
C8H4O3 + C6H6 --> C14H8O2 + H20
b) What mass of Anthroquinone and of H2O will be produced with a 100% yield?
[I don't want an answer, I'd just like to know how to approach this problem]
c) What percent yield is achieved if 1.96 x 10^3 g of anthro is produced? [same- how would I do this?]
For b), you know that one mole of phthalic anhydride plus one mole of benzene goes to one mole of anthroguinone plus one mole of water. I presume they tell you the mass of one of the reactants, so you can then figure out how many moles are present, then you know how many moles of anthroquinone will be produced.
Same for c): figure out how many moles that is, and go from there.
Thank you!
You're welcome!!
Somehow I think you missed an important point: what was the starting mass of phthalic anydride?
