The cubic unit cell of a metal (molar mass=63.55 g mol^(-1))has an edge length of 362pm. Its density is 8.92 g cm^(3). The typeof cell is

Answer»

FCC
BCC
Simple cubic
None of these

Solution :`Z=(d times a^(3)timesN_(0))/M`
`=((8.92 g CM^(-3))times(3.62times10^(-8)cm)^(3)times(6.02times10^(23)MOL^(-1)))/(63.55 g mol^(-1))`
`=(8.92times47.44times10^(-24)times6.02times10^(23))/(63.55)`
=`4.001`
