Copper crystallises into a fcc lattice with edge length '3.61 x10^-8 cm'. Show that the calculated density is in agreement with its measured value of '8.92 g cm^-3'

Explanation

`M=63.5 g mol^-1 , z=4: a_t=3.61 xx 10^-3 cm `

`d=z M/a^3 N_A=4 xx 63.5/(3.61 xx 10^-8)^3 xx 6.02 xx 10^23`

=`8.96 gcm^-3`
