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)`.
Text Solution
Verified by Experts
Atomic mass `=("Density" xx Av. no . xx "Volume of unit cell")/(z)` `[:' z=4(fo r f.c.c.)]` `:.` Density `=(63.55xx4)/(6.023xx10^(23)xx(3.61xx10^(-8))^(3))` `=8.97g//cm^(3)` The calculated value of `8.97g//cm^(3)` is closer to given value `892g//cm^(3)`.
