CaC
20.7 g 6.81g +
As per the law of Conservation of mass , in any chemical reaction, the total mass of products is equal to the total mass of the reactants.
mass of C
mass of C
mass of C
% yield of a Product Z = mass of product Z x 100 / mass of reactant
% yield of Product C
% yield of Product CaO = 6.81g x 100 /20.7 = 32.89%
