Answer:

Law of definite proportion states that a given compound always contains exactly the same proportion of elements by weight.

Case 1: Ca2.8g O0.8g ⟹1g of O reacts with =0.82.8=3.5g of CaO

Case 2: 3.5g 1g⟹1g of O reacts qith 3.5g of CaO.

Ratio of O reacting with Ca to form CaO is 1:1.

Hence results illustrate the law of definite proportion
