Even without working it out,the answer is obvious... because both A and D are the same thing..
Eliminate B...since it's not tested this way..
C is definitely correct ✔️
The answer is A. (Law of Constant Composition or Definite Proportion).
.
The law states that all pure sample of a particular chemical COMPOUND contain similar ELEMENTS combine in the SAME proportion by MASS. i.e a pure sample of 2.25g of the first oxide of copper and 2.5g of the second oxide of copper contain the same proportion by Mass..
.
Correct it pls.
