PLEASE ANSWER ALL

atomic radius of metal

Found density is 2.80

Diameter is 1.25cm

1. what is the packing of the atoms in the unit cell of aluminum?

2. calculate the mass of a single atom of aluminum based upon the molar mass given in the periodic table

3 using your density (2.80) of aluminum calculate (a)the volume of the unit cell

(b) edge length, a, of the unit cell

(c) aromic raduis of aluminum

4. using the known density of aluminum calculate

(a) the volume of the unit cell

(b) edge length, a, of the unit cell

(c) atomic radius of aluminum

5. determine the percent error of the calculated radii using answers from 3 and 4
