Proportion Hydrogen by mass: (1.008 x 12) / 180.16 = 0.0671 Fructose (C6H12O6), molar mass 180.16g/mol. Density as a solid 1694 kg/m^3. Proportion Hydrogen by mass: (1.008 x 12) / 180.16 = 0.0671 Sucrose (C12H22O11), molar mass 342.30g/mol. Density as a solid 1587 kg/m^3. Proportion Hydrogen by mass: (1.008 x 22) / 342.30 = 0.0648 Thus a DTon (14m^3) of each has a following characteristics: Mass Mass of Hydrogen Glucose 1.540 x 14 = 21.560 0.0671 x 21.560 = 1.45 tonnes Fructose 1.694 x 14 = 23.716 0.0671 x 23.716 = 1.59 tonnes Sucrose 1.587 x 14 = 22.218 0.0648 x 22.218 = 1.44 tonnes Oleic acid, C18H34O2, (the primary constituent of olive oil) is even better. Molar mass 282.47 g/mol. Density at room temperature 895 kg/m^3. Hydrogen proportion by mass (1.008 * 34) / 282.47 = 0.1213. Thus hydrogen per DTon: 14 x .895 x 0.1213 = 1.52 tonnes. Looks like high-density hydrogen comes from agricultural worlds. -- Rupert Boleyn <xxxxxx@gmail.com> Chief Assistant to the Assistant Chief
