Answer:
CaC

3
--------> CaO + C
O
2
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
O
2
+ mass of CaO is equal to the mass of CaC
O
3
.
mass of C
O
2
+ 6.81g = 20.7g
mass of C
O
2
= 20.7g- 6.81g = 13.89g
% yield of a Product Z = mass of product Z x 100 / mass of reactant
% yield of Product C
O
2
= 13.89 x 100 / 20.7 = 67. 10%
% yield of Product CaO = 6.81g x 100 /20.7 = 32.89%
