Dear Ashfaque Alam, this is what you asked.

Density table ρ of materials g / cm3 (kg / dm3) and coefficients K = ρ / 7.85

The name of the material, mark ρ, g / cm3 K = ρ / 7.85

Cd 8,64 1,10

Mn 7,2-7,4 0,91-0,94

Te 6,25 0,79

Dear Andrii Shevchenko thanks for the reply. But the values you mentioned are all elemental density. I need the value of density of the compound CdMnTe (Cadmium Manganese Telluride). Hope this is clear now.
