"Please do the calculations to show how much more buoyant hydrogen is than helium in air." -> everyone knows Hydrogen explodes so we banned use of it in blimps etc., but it also doesn't provide that much more lift. It's 1/2 the density, but air is 10x heavier, so the proportional difference is only 8.5%.
