where x (g/mol) is the molar mass of the starting metal, 100% is the weight of the starting metal, 16 (g/mol) is the molecular weight or molar mass of oxygen, and y% is the weight gained by heating. For example, let us say we are starting with 100% of metal. That corresponds...
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就是16.0X2 即是32.0... 1 MOLE的SODIUM CHLORIDE的质量就用FORMULAR M...
