Question

Calculate the atomicity of the following:
1. NH3
2.H₂O
3.H2SO4
4.CH3COOH
5.S8
6.KMnO4
7. K2Cr2O7
8. Cl2
9. NH4Cl
10. SO2

Answer 1

Answer:

1. NH3 = It have 4 atoms. Therefore atomicity is 4.

2. H2O = 2 hydrogen atoms + 1 oxygen atom = 3 atom. Therefore atomicity is 3.

3. H2SO4 = It have 7 atoms. Therefore atomicity is 7.

4. CH3COOH = The atomicity is 8.

5. S8 = The atomicity is 8.

6. KMnO4 = The atomicity is 6.

7. K2Cr2O7 = The atomicity is 11.

8. CI2 = The atomicity is 2.

9. NH4CI = Cl = 1. H = 4. N = 1. Therefore, 1+4+1=6. So, the atomicity is 6.

10. SO2 = The atomicity is 8.
