Copper crystallizes into a fcc lattice with edge length `3.61 xx 10^(-8)` cm. Calculate the density of the crystal (Atomic mass of copper = 63.5 g/mol and Avogadro number = `6.022 xx 10^(23) mol^(-1)`)

Text Solution

Verified by Experts

`d = (ZM)/(a^(3) N_(A))`
`d = (4 xx 63.5)/((3.61)^(3) xx 10^(-24) xx 6.022 xx 10^(23))`
`d = (254)/(28.33)`
d = 8.9 `g//cm^(3)`
