For iodine the enthalpy of sublimation is 62.0 kJ/mol. The entropy of sublimation is 145 J/(K mol).
Calculate the sublimation temperature (Kelvin).

i am doing this according to your units:
assuming that K in the unit for entropy stands for temperature in Kelvin, then by dividing enthalpy/entropy will give you the answer in Kelvins.
but you have to be careful of kJ and J, 62000/145 = 427.6

Didn't you ask this same question yesterday or some time? The equation you'll need to use is:
DG=DH-TDS (D=delta)
In any equilibrium and phase change, DG will equal 0. So, DH=TDS. You know DH, and you know DS, so you can solve for T.
