A pair of students performs an experiment in which they collect 27 g CaO from the decomposition of 41 g CaCO3. Are these results reasonable? Explain your answer using percentage yield.

Answer 1

41 g CaCO3 should produce how much CaO?
%CaO in CaCO3 = (56/100)*100 = 56%.
So 41 g CaCO3 should produce 41*0.56 = about 23 g CaO. The students collected 27 grams. Does that sound reasonable to you. What would their percent yield be?

Answer 2

what is my percent yiel if i had 1.46 grams of copper to start with and ended with 2. 47 grams of copper?
