Question

2.0 g of a metal burnt in oxygen gave 3.2 of its oxide 1.42 g of same metal heated in steam gave
​

Answer 1

Answer:

Law of constant composition is shown.

Explanation:

Since, in the first 3.2g of metal oxide contains 2 g of metal so 100 g of metal oxide will contain 2/3.2 * 100 = 62.5g.

So, % of metal in first compound will be 62.5%.

For the other, 2.27 g of metal oxide will have 1.42/2.27 * 100 = 62.55 g of metal thus 62.5% of the metal is in the second compound.

Thus, we see that the % of metal in the metal oxide is same for both so it is law of constant composition.
