The compound CuCl has ZnS structure and the edge length of its unti cell is 500 pm. Calculate its density
(At mass Cu = 63, Cl = 35.5, `N_(0)=6.02xx10^(23)"mol"^(-1)`)

Text Solution

Verified by Experts

`M=(63+35.5)"g mol"^(-1)`
`=98.5"g mol"^(-1)`
`a=500"pm"=5xx10^(-8)"cm",z`
(for ZnS structure) = 4
`N_(A)=6.02xx10^(23)"mol"^(-1),d=?`
d = =
`="g cm"^(-3)=5.24"g cm"^(-3)`
