WitrynaSo the equation to calculate the impurity percentage is impurity percentage equals the mass of the impurities divided by the mass of the sample times 100 percent. The … Witryna26 mar 2024 · Further, it is unclear where your equation for the chemical potential comes from. The chemical potential stays the closer to the intrinsic level the higher the temperature and the lower the impurity concentrations are. If you let the impurity concentration go to zero, the chemical potential will approach the intrinsic level. north face china factory
