I was wondering how they got 0.25 mols of h2. I know for every 2 moles of electron is consumed 1 mole of the hydrogen is produced. How is 0.25 mols of hydrogen gas calculated ??

Follow the formula on how they got mols of Fe(s) and you should get .25 mols of H2 also.

I'm getting 0.5 g as well, OP did figure it out?!
(6*3600 sec)*(2 Amps)/(96500/2)*(2g/mol)=0.45 g, no?

^OP asked for how they got .25 mols, which is .5 grams. I got confused by your post a bit lol.
