L. 2.0 g of a metal burnt in oxygen gave
3.2 g of its oxide. 1.42 g of the same
metal heated in steam gave 2.27 of its
oxide. Which law is verified by these
data ?

Hey Dear,
◆ Answer -
Law of definite proportion
# Law of definite proportion -
It states that a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation.
● Explanation -
When 2.0 g of metal burns with oxygen, it gives 3.2 g of its oxide.
Ratio of M:O = 2/3.2
Ratio of M:O = 0.625
When 1.42 g of metal is heated with steam, it gives 2.27 g of its oxide.
Ratio of M:O = 1.42/2.27
Ratio of M:O = 0.625
Hence, it is proved that ratio of metal to oxygen in its oxide is same (0.625) irrespective of its method of preparation.
This is called Law of definite proportion.
