Question

what is atomicity ? calculate the atomicity of CuSO4, HCI, PBno3 , NaCI, H2Co3​

Answer 1

Answer:

Atomicity is  the total number of atoms that constitute a molecule.

Atomicity of CuSO4=6

Atomicity of HCl= 2

Atomicity of NaCl=2

Atomicity of H2CO3=6

Answer 2

Answer:

Atomicity of :

1. CuSO₄ = 6
2. HCl = 2
3. Pb(NO₃)₂ = 9
4. NaCl = 2
5. H₂CO₃ = 6

Explanation:

$\blacksquare$ Atomicity is defined as the total number of atoms in a molecule

Hence,

$\blacksquare$ Atomicty of CuSO₄

= Number of C-atoms + Number of S-atoms + Number of O-atoms

= 1 + 1 + 4

= 6

$\blacksquare$ Atomicity of HCl

= Number of H-atoms +  Number of Cl-atoms

= 1 + 1

= 2

$\blacksquare$ Atomicity of Pb(NO₃)₂

=  Number of Pb-atoms +  Number of N-atoms +  Number of O-atoms

= 1 + 2 + 6

= 9

$\blacksquare$ Atomicity of NaCl

=  Number of Na-atoms +  Number of Cl-atoms

= 1 + 1

= 2

$\blacksquare$ Atomicity of H₂CO₃

=  Number of H-atoms +  Number of C-atoms +  Number of O-atoms

= 2 + 1 + 3

= 6
