Question

Sulphur exist in different allotropic forms like $S_{2}, S_{6}$ and $S_{8}$ etc. If equal moles of these three forms are taken in separate containers, then the ratio of number of atoms present in them respectively is:

(A) $1: 3: 4$

(B) $1: 1: 1$

(C) $12: 4: 3$

(D) $4: 3: 1$

Answer 1

	S2	S6	S8
Mole	n	n	n
Molecule	n × NA	n × NA	n × N​​​​​A ​​​​​​
Atoms	n × NA ×2	n × NA × 6	n × NA × 8

Therefore, Ratio of atoms of S = 2 : 6 : 8 = 1 : 3 : 4

So, The correct option of this question is (A)
