A chemist treated 22.99 g of galantamine with sulfuric acid to make the sulfate salt: $\ce{2C17H21NO3 + H2SO4 -> (C17H22NO3)2SO4}$

The mass of salt isolated was 24.65 g. Determine the percentage yield of the salt. Use section 7 of the data booklet.

(i) If the reaction has a percentage yield of 80 %, calculate the mass, in g, of benzene that would be produced from 2.0 kg of cyclohexane. (ii) Calculate the atom economy for this reaction, as a percentage.
