A metal crystallizes in a body centered cubic unit cell. The radius of one atom = 1.67 x 10 -8 cm. The density of the metal is 0.535 g/cm 3 . What is molar mass of metal?
Prompt 1 What is the mass of a unit cell?
Prompt 2 How many atoms are in a BCC structured unit cell?
Prompt 3 With the length of cube in hand, we could calculate the volume of the unit cell by cubing it. What is the volume?
Prompt 4 What is the mass of each atom?
Prompt 5 What is the molar mass of that metal?
Prompt 6 What is the relationship between radius and length in a BCC cell? We have the radius, can we calculate the length of the unit cell?
