Calculate the surface energy of the (100) surface of niobium. The enthalpy of atomization of niobium is 745 kJ/mole. Express your answer in units of J/cm2.

9.09e-3 J/cm2

not right

no right

2.8*10^-4

how did you get that???

its wrong

cheat 3.091 x 10^-6 joules/cm2

It still wrong answer.

6.23 e -3 finally is correct

nop. still wrong
