A) 2
B) 4
C) 6
D) 8
Correct Answer: D
Solution :
Let atomicity of sulphur is n, then it exists as\[{{S}_{n}}\]. \[\therefore \] Molar mass, \[m=32\,n\] Now from. \[\Delta {{T}_{f}}=\frac{1000\,w\,{{K}_{f}}}{m\,\,w}\] \[0.010=\frac{1000\times 2.56\times 0.1}{m\times 100}\] or = 256 or \[32\,\,n\,\,=256\] or \[n=\frac{256}{32}=8\]You need to login to perform this action.
