`2.56g` of sulfur in `100 g` of `CS_(2)` of has depression in freez point of `0.01^(@)C.K_(f)=0.1^(@)` mol `al^(-1)`. Hence, he atomicity of sulfur is `CS_(2)` is

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaT_f=K_fm`
`10^(-2)=0.1xxmimpliesm=0.1 m`
molality=`(2.56xx1000)/(Mxx100)impliesM=256implies"atomicity"=256/32=8`
