Copper crystallizer into an fcc lattice with edge length `3.61 xx 10^(8) cm`, Show that the calculated density in in agreement with its measured value of `8.92 g cm^(3)`.

Answer

`8.96 g cm^(-3)`

Explanation

Density = `(4 xx 63.5)/((3.61 xx 10^(-8))^(3) xx (6.022 xx 10^(23)))`
`= 8.96 g cm^(-3)`
