Density

Generally the equation for the Velocity  is mathematically given as

[tex]V_c=a^3=(2\pi Fe^{2+}+2\pi S^{2-})^3\\\\Therefore\\\\V=a^3(2\pi*0.088+2\pi 0.184)^3\\\\V=16.98*10^{-23}\\\\Therefore\\\\\phi=n\frac{PFeion+PSion}{VNa}\\\\\phi=3*\frac{55.85+32}{16.9*10^{-23}*6.023*10^{23}}[/tex]

  • [tex]\phi=2.56h/cm^3[/tex]
  • [tex]\phi=2.56h/cm^3[/tex]
