Question

a) Define atomicity.What is the atomicity of phosphorus.

(b) Which postulate of Dalton’s atomic theory is the result of law of

conservation of mass?

(c) How many atoms are present in in a molecule of (i) HNO3 (ii) C6H12O6

​

Answer 1

Explanation:

(a)Atomicity is the number of atoms of an element present in one molecule of that element. The number of atoms present in a molecule of phosphorus are 4. So the atomicity of phosphorus is 4.

(b)Which postulate of Dalton's atomic theory is the result of the law of conservation of mass? Solution : The postulate of Dalton's “Atoms are indivisible particles, which can neither be created nor destroyed in a chemical reaction” is the result of the law of conservation of mass.

(c)So a molecule of glucose has 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms.

Answer 2

Explanation:

1. Atomicity is the number of atoms of an element present in one molecule of that element. The number of atoms present in a molecule of phosphorus are 4. So the atomicity of phosphorus is 4.t.
2. Solution : The postulate of Dalton's “Atoms are indivisible particles, which can neither be created nor destroyed in a chemical reaction” is the result of the law of conservation of mass.
