An element has atomic mass 93 g mol^(-1)...

An element has atomic mass `93 g mol^(-1)` and density `11.5 g cm^(-3)`. If the edge length of its unit cell is 300 pm, identify the type of unit cell.

Text Solution

Verified by Experts

The correct Answer is:
` 38 . 4 g cm ^(-3) `
`p = (Z xx M)/(a^(3)xxN_(0)) , Z = ( p xx a^(3) xx N_(0))/M = (( 11.5 " g cm"^(-3)) (300xx 10^(-10)"cm")^(3)(6.023 xx10^(23) "mol"^(-1)))/(93" mol"^(-1)) = 2.01 =2 `
Hence, the type of unit cell in BCC.
