Using the principles already applied to the structures described before, the team now constructed new elements they hoped would assemble in a self - limiting fashion into cage structures under the right conditions. (sciencedaily.com)
The average methane clathrate hydrate composition is 1 mole of methane for every 5.75 moles of water, though this is dependent on how many methane molecules «fit» into the various cage structures of the water lattice. (princeton.edu)
The nominal methane clathrate hydrate composition is (CH4) 4 (H2O) 23, or 1 mole of methane for every 5.75 moles of water, corresponding to 13.4 % methane by mass, although the actual composition is dependent on how many methane molecules fit into the various cage structures of the water lattice.
