1000 mls X (0.5/100) = 5 mls
rabidcrayon: 0.05 would be 5% not 0.5%

The previous answers are valid if you are talking about a 5% solution BY VOLUME. Solutions are normally given in concentrations described by mass in volume (as in 5 g/L).
I am not certain exactly what a volume% signifies in this case as iodine is normally a solid crystal when it is not dissolved.
A .5% by-wieght solution (presumeably in water) would be slightly different than the answers given. You would need the density of iodine.
I suggest you look very carefully at the question and make sure you are really chasing the right result.

just multiply 0.5% with 1000 ml
0.5% = 0.05
0.05 x 1000 = 50 ml iodine
*edit*
my bad, mikeys right. its 5 ml

The answer is 5 mL. multiply 1000 mL times the concentration, 0.005 (which is 0.5% numerically).
Hope this helps. :)
