WebThe effect of dissolved carbon dioxide and ethane on methane solubility has been determined at 302 {sup 0}F. Also the solubility of crude oil and water in methane has been determined over a broad range of temperatures and pressures. The solubility of methane is raised by increasing pressure and temperature (above about 170 {sup 0}F). WebWater has a very high dielectric constant and this allows salts to dissolve in water with dissociation. The dielectric constant tells us how well the solvent is able to separate ions. ... water 100 deg C 18 g/mol 18 mL: ethanol 78 deg C 46 g/mol 36.3 mL: pentane 36 deg C 72 g/mol 45 mL: decane 174 deg C 142 g.mol 104 mL: name boiling point mass ...
