Página 131 - The actual weight of this cube of hydrogen, at the standard temperature and pressure mentioned, is 0'0896 gramme; a figure which I earnestly beg you to inscribe, as with a sharp graving tool, upon your memory. There is probably no figure in chemical science more important than this one to be borne in mind, and to be kept ever in readiness for use in calculation at a moment's notice. For this litre-weight...
