Find the activity coefficient from the given ionic strength, µ, for the following ion.
F –when µ = 0.0080

Calculate the activity coefficient of H⁺ using the extended Debye-Huckel equation for a solution comprised of H⁺ and I ^–. Given that H⁺ has a size of 9.00 x 10^-10 m and the molar concentration of the solution is 0.075. 

${\log }_{}\gamma =\frac{-0.51z^2\sqrt{\mu }}{1+\left(\frac{\alpha \sqrt{\mu }}{305}\right)}$
