Q12.83 P - Chemistry: Molecular Nature Of Matter And Change

Question

Besides the type of unit cell, what information is needed to find the density of a solid consisting of identical atoms?

Step-by-Step Solution

Answer

Besides the type of unit cell, the molecular weight and the diameter of atoms should be known to find the density of solid consisting of the identical atoms.

Step1: Density of solid

The density of any crystalline solid is equal to the density of its unit cell. The crystalline solid the repetitive 3-D array of its unit cell.

Step2: Information for density calculation

For the density calculation, molecular weight of the atoms should be known and also to calculate the volume, the diameter of atom should also be known apart from the type of unit cell.
