Question

define law of definate proportions in easy language​

Answer 1

Answer:

Law of definite proportion states that all samples of a given chemical compound have the same elemental composition by mass

Answer 2

Answer :

Law of definite proportions : The ratio of the masses of elements in any compound is constant regardless of its source or its preparation i.e., a given compound always contains exactly the same proportion of elements by weight.

It is sometimes also referred to as law of definite composition$.$

Let's understand by an example :)

➝ In an experiment, 2.4g of iron oxide on reduction with hydrogen gave 1.68g of iron. In another experiment, 2.9g of iron oxide gave 2.09g of iron on reduction.

Above data illustrate Law of definite proportion.

Explanation :

◈ In first experiment,

2.4g of iron gave 1.68g of iron.

Mass of iron oxide = 2.4g

Mass of iron = 1.68g

Mass of oxygen = 2.4-1.68 = 0.72

Ratio of maases of iron and oxygen

• 1.60/0.72 = 7 : 3

◈ In second experiment,

Mass of iron oxide & 2.9g

Mass of iron = 2.09g

Mass of oxygen = 2.9-2.09 = 0.81

Ratio of masses of iron and oxygen

• 2.09/0.81 = 7 : 3

፨ The same ratio confirms that these experiments clarify law of definite proportions.
