Document Summary
Name: _____________________: a pure metal is determined to be a face centered cubic with an a value of. Therefore volume = a3 = 5. 89 x 10-23 cm3. 12. 02g/ml x 5. 89 x 10-23 ml = 7. 08 10-22g/cell 4 atoms/cell = 1. 79 10-22 g/atom. 1. 79 10-22 g/atom x 6. 023 x 1023 atoms/mol = 106. 5 g/mol therefore pd from periodic table. 2)for the phase diagram given below, explain what process is represented by each arrow, what phases are represented by each letter and the meaning of points (1) and (2). /3: region a represents (solid, liquid or. Gas) __solid________________: region b represents (solid, liquid or. Gas) _____liquid________________ e r u s s e r. Point (2) represents_____ supercritical temperature and pressure __ /4: kbr, cao, sro, all have about the, br2, f2, n2, all have about the, sio2, co2, no2, mercury c) air d) supercritical co2.
