The density of totally crystalline nylon 6,6 at room temperature is 1.213 g/cm3. Also, at room temperature

Question:

The density of totally crystalline nylon 6,6 at room temperature is 1.213 g/cm3. Also, at room temperature the unit cell for this material is triclinic with the following lattice parameters:

a = 0.497 nm ..................... Î± = 48.4(

b = 0.547 nm ..................... Î² = 76.6(

c = 1.729 nm ..................... Î³ = 62.5(

If the volume of a triclinic unit cell, is a function of these lattice parameters as

Determine the number of repeat units per unit cell?
