Answer:
The answer is "Law of definite proportion".
Explanation:
When 2.0 g of a metal burnt in oxygen gave 3.2 g of its oxide.
The ration of metal: oxide = 2/3.2
The ration of metal: oxide = 0.625
When 1.42 g of the same metal heated in steam gave 2.27 of its oxide.
The ration of metal: oxide = 1.42/2.27
The ration of metal: oxide = 0.625
Hence proved that the ratio of metal to oxygen in its oxide is equal i.e. 0.625.
It shows the law of definite proportion which states that" A given chemical compound always contains its component elements in a fixed ratio and does not depend on its source and method of preparation".
