Answer 1

Explanation:

Let the mass of the compound is 100 gm

Mass of zinc =67.1 gm

Mass of sulphur =100−67.1=32.9 gm

Ratio of mass Zn:S=67.1:32.9

Ratio of moles Zn:S=

65.3

67.1

:

32

32.9

Nearest integer ratio is 1:1

So, the compound is ZnS

x+y is 1+1=2.

Answer 2

Answer:

Let the mass of the compound is 100 gm Mass of zinc = 67.1 gm Mass of sulphur = 100 - 67.1 = 32.9 gm Ratio of mass Zn : S = 67.1 : 32.9 Ratio of moles
