Oxygen gas is used as a reactant in many hydrometallurgical processes. However, oxygen is sparingly soluble in aqueous electrolyte solutions, and the driving force for its masstransfer from the gas to the aqueous phase is also very low. Hence, the mass-transfer of oxygen depends significantly ...
举点例子啦-V- 1 MOLE的SODIUM ATOM的RELATIVE ATOMIC MASS就是23.0 MOLAR MASS就是23.0gmol^-1... 1 MOLE的OXYGEN GAS的质量则用RELATIVE MOLECULAR MASS来表达 因为OXYGEN GAS是SIMPLE MOLECULAR STRUCTURE OXYGEN GAS的MOLECULE就是由两粒OXYGEN ATOM组成 所以OXYGEN GAS的RELATIVE MOLECULAR MASS就...
