The density of solid w is 19.3 g/cm^3. how many atoms are present per cubic centimeter of w?
atoms cm^3

as a solid, w adopts a body-centered cubic unit cell. how many unit cells are present per cubic centimeter of w?
unit cells/cm^3

what is the volume of a unit cell of this metal?
cm^3

what is the edge length of a unit cell of w?

Atoms present per cm³ of Ag =

Unit cells which are present per cubic centimeter of W =

Volume =

Edge length =

Explanation:

Given that:-

The density of the solid W = 19.3 g/cm³

Molar mass of W = 183.84 g/mol

So, Moles present per cm³ of Ag = =0.105 mol/cm³

Also, 1 mole = atoms.

So,  

Atoms present per cm³ of Ag =

Thus, answer =

In BCC, the number of atoms  in the unit cell = 2

So,

Unit cells which are present per cubic centimeter of W =

Unit cells which are present per cubic centimeter of W =

The reciprocal of the unit cell/cm³ is the volume of the unit cell.

So,

Volume =

Also, Volume =

Thus, edge length = =

Edge length =

they are both synthetic elements
