Percent yield
80 %
Atom economy
83.333 %
Actual yield
8 g
Theoretical yield
10 g
Formula and working
% yield = actual ÷ theoretical × 100; atom economy = mass of desired product ÷ total mass of products × 100
- 1
Collect the inputs
Actual yield = 8 g; Theoretical yield = 10 g; Molar mass of desired product = 100 g/mol; Total molar mass of all products = 120 g/mol
