An element occurs in bcc structure with ...

An element occurs in bcc structure with edge length of 288 pm. Its density is `7.2 g//cm^3`
Calculate atomic mass of element.

Text Solution

Verified by Experts

For bcc, Z=2 `A=(rhoxxN_0xxa^3)/(Z)`
a=`(288xx10^(-10))` cm
`rho=7.2 "g/cm"^3`
`A=(7.2xx6.02xx10^23xx(288xx10^(-10))^3)/2`
A=52 g/mol
