Metallic vanadium crystallizes in a body-centered cubic lattice, with one V atom

Chemistry
Tutor: None Selected Time limit: 1 Day

Metallic vanadium crystallizes in a body-centered cubic lattice, with one V atom per lattice point. If the metallic radius of V is 130 pm, what is the volume of the unit cell in pm3 and in cm3?

 pm3
 cm3

4r = 4 *130 pm = 520 pm 

d2 + (d√2)2 = 5202

 d = 300.22 pm = 300.22 * 10^-10

 a. Volume = (300.22 )^3 pm^3

            = 27060022.2167 pm^3

            = 270.60022 * 10^5 pm^3

b.    27060022.2167  * 10^-30 cm^3

       = 270.60022 * 10^-25 cm^3

Refer to the following phase diagram (not to scale!) for fluorine :

At a pressure of 1 atm, the temperature 53.5 K is called the of F2 .
The normal boiling point for F2 is at  K
The triple point pressure for F2 is  atm

The critical pressure for F2 is 55.0 atm. At temperatures above 144.1 K and pressures above 55.0 atm, F2 is a .

F2 is a  at 1.60E-4 atm and 96.1 K.
F2 is a  at 1.00 atm and 60.4 K.
F2 is a  at 25.7 atm and 42.3 K.
