how to you calculate % yield from a chemical reaction
Clark JH. Chemistry goes green. Nat Chem 2009;1:12-3.
You need to be able to calculate the atom economy of a reaction to form a desired product from the balanced equation and perhaps explain why a particular reaction pathway is chosen to produce a specified product given appropriate information such as atom economy, yield, rate, equilibrium position and usefulness of by-products.
PRACTICAL APPROACH TO GREEN CHEMISTRY
many of the atoms of the reactants not being incorporated into the desired product (ibuprofen) but into byproducts.

2. Atom Economy
Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product.
the manufacture of a chemical like aspirin
6. Design for Energy Efficiency
Energy requirements of chemical processes should be recognised for their environmental and economic impacts and should be minimized. If possible, synthetic methods should be conducted at ambient temperature and pressure.
