Composition of the tank is irrelevant. Steel and Aluminium tanks
of the same size have the same buoyancy shift.

An 80 has six pounds of air molecules when full. A pint's a pound
the world around, so the 80 would need three extra quarts of air
in your suit to balance the gas molecules when full.

If you had a 72, it would be a touch less than three quarts, but
close (closer than you think, an AL80 is really a AL77), if you
had a bigger tank. it would be a bit more.
