Answer to Question #293969 in General Chemistry for Gamma

Question

The equation for a reaction that can be used to manufacture lithium carbonate is

2Li2O2 + 2CO2 → 2Li2CO3 + O2

What is the atom economy for this reaction?

Answer 1

Atom economy=(Mass of product/sum of relative molecular mass of all reactants)x100

Atomic mass of Li=7, O=16, C=12.

Atom economy= (mass of lithium oxide formed/mass of reactants used)x100

			=(148/180)x100
            =82.22%
