What is the molar mass of potassium chloride?Potassium ChloridePotassium and chlorine bond to form potassium chloride. Potassium ions have a +1 charge and chloride ions have a -1 charge. They stick together in a 1:1 ratio giving us the formula KCl....
例如：molar mass of CO2 = 44 g/mol； molar mass of NaCl = 58.5 g/mol 简单来说，只有 molar mass 的 unit 是 g/mol，而其他都是没有 unit 的 relative mass。以 H2SO4 为例（Pure H2SO4 is molecular）： Relative atomic mass of H = 1 Relative atomic mass of S = 32 Rela...

Percent composition can be expressed as mass percent (w/w %) which is the percentage of the mass of solute over the mass of solution. Or simply concentration could be expressed in units of mass per volume (i.e., g/L, mg/L). We can divide the substances that dissolve in water into...
