The density of a metal is `9.50g cm^(-3)` Calculate the number of kilograms per cubic metre.

Text Solution

Verified by Experts

`((9.50 g)/(cm^(3)))((1 kg )/(10^(3)g))((10^(2)cm)/(m ))^(3) = 9.50xx10^(3) kg m^(-3)`

Silver crystallises in a face-centred cubic unit cell. The density of Ag is 10.5 g cm^(-3) . Calculate the edge length of the unit cell.

Density of a unit cell is the same as the density of the substance. So, if the density of the substance is known, we can calculate the number of atoms or dimensions of the unit cell. The density of the unit cell is related to its formula mass (M), number of atoms per unit cell (z), edge length (a in cm), and Avogadro's constant N_(A) , as rho=(zxxM)/(a^(3)xxN_(A)) Q.
