You can see the exact weight in my tank calculator at
http://henrik.synth.no/scuba/tanks.html.

300 bar tanks are much heavier than same size (in litres) 200 bar tanks.
They're not used much by tec divers because of that, and because mixing gas
is difficult @ 300 bars. 232 bar tanks is considered the sweet spot.
