Concentration

• concentration (ריכוז)
  • molarity (or molar concentration) (ריכוז מולרי, מולריות)
    • $c=\frac{n}{V}$ (also denoted $M$)
    • $[\mathrm{A}]$ is the molarity of $\mathrm{A}$
    • SI unit: $mol/{\mathrm{m}}^3$
    • other units: $mol/L=\mathrm{M}$ (molar)
    • equivalent concentration (or normality) $\mathrm{N}=\frac{\mathrm{eq}}{\mathrm{L}}$
      • $\text{eq/L}=\text{molarity}\times \text{valence}$
  • mass concentration (ריכוז מסה)
    • ${\rho }_i=\frac{m_i}{V}$
  • volume concentration ${\sigma }_i=\frac{V_i}{V}$
  • number concentration
