Phosphorus trichloride contains 22.57 % of phosphorus , phosphine ( PH3) contains 91.18% of Phosphorus while HCL gas contain 97.23% of chlorine by calculation which law is illustrated by these data.?
Verified Answer
Phosphorus trichloride contains 22.57 % of phosphorus , phosphine ( PH...
Let us fix 1g of phosphorus (P) as the fixed weight.
In phosphorus trichloride (PCl3)
Weight of phosphorus = 22.57g
Weight of chlorine = 100 – 22.57 = 77.43g
22.57g of phosphorus have combined
with chlorine = 77.43g
1.0g of phosphorus has combined
with chlorine = 77.43/22.57g = 3.43g
In phosphine (PH3)
Weight of phosphorus = 91.18g
Weight of hydrogen = 100 – 91.18
= 8.82g
91.18g of phosphorus have combined
with hydrogen = 8.82g
1.0g of phosphorus has combined
with hydrogen = 8.82/91.98 g = 0.097g
Thus, the ratios by weights of chlorine and hydrogen combining with a fixed weight of phosphorus in
the two compounds is 3.43:0.097 (This ratio is not the same) ....(i)
In hydrochloric acid gas (HCl), Weight of chlorine = 97.23g
Weight of hydrogen = 100 – 97.23 = 2.77g
Thus, chlorine and hydrogen have combined in the ratio 97.23:2.77 ....(ii)
Let us compare the two ratios.
These are related to each other as = 3.43/0.097 : 97.23/ 2.77 = 35.37:35.10 or 1:1 (approximately)

Illustration of Law
The law illustrated by these data is the Law of Definite Proportions, also known as the Law of Constant Composition.
Explanation
The Law of Definite Proportions states that a given chemical compound always contains the same proportion of elements by mass. In other words, the ratio of the masses of the constituent elements in a compound is always fixed and constant.
The data provided in the question show that the percentage composition of the elements in different compounds is fixed and constant. For example, phosphorus trichloride always contains 22.57% of phosphorus and 77.43% of chlorine by mass. Similarly, phosphine always contains 91.18% of phosphorus and 8.82% of hydrogen by mass, while HCl gas always contains 97.23% of chlorine and 2.77% of hydrogen by mass.
These fixed and constant percentages of elements in compounds are in accordance with the Law of Definite Proportions. This law is a fundamental principle of chemistry and is used to determine the chemical formula of a compound. By knowing the percentage composition of a compound, we can calculate the ratio of the masses of the constituent elements and hence determine the chemical formula of the compound.
In conclusion, the Law of Definite Proportions is illustrated by the fixed and constant percentage composition of elements in different compounds, as shown by the data provided in the question.
