Answer to Question #144777 in General Chemistry for Joshua

Question

Molybdenum has an atomic raduis of 0.145nm. The volume of its cubic unit cell is 0.0375 nm^3 . what is the geometry of the molybdenum unit cell?

Answer 1

that. First, a=V^1/3

V=0.0375; therefore,

a=(0.0375^1/3, then

0.0375^1/3*1.732/4= 0.145 and that is the radius given in the problem. sqrt 3 = 1.732
