Answer:
Theoretical yield is 20%.
Explanation:
Percent yield = [(actual yield)/(theoretical yield)]
%
Theoretical yield is calculated amount of product by using stoichiometric ratio between reactant and product.
Actual yield is the amount of product which is experimentally obtained.
Here theoretical yield is 20.0 g and actual yield is 4.0 g.
So, percent yield =
% = 20%
Answer:
72.71 %
Explanation:
For oxygen: mass % O = (mass of 1 mol of oxygen/mass of 1 mol of CO2) x 100. mass % O = (32.00 g / 44.01 g) x 100. mass % O = 72.71 %
