How long does it take to produce H2 in a closed beaker

hi,
I've got a problem which I cannot solve. The problem says that How long does it take to produce H2 in a closed beaker with volume 5l pressure 10Mpa and temp. 20 C with a current of 0.7A. First thing I did was to calculate the amount of H2 in that beaker. Assuming that it behaves ideally I calculated that there should be about 20.515 moles of hydrogen. And what now ? Is there any formula for this ?
thanx

Re: Electrolysis

How fast can you produce the hydrogen gas with a 0.7A current?

Re: Electrolysis

what's the time needed for electrolysis to produce that amount of H2
