    activity=gamma*concentration (gamma is the activity coefficient).  So, gamma=activity/concentration.

    "activity" is defined by reaction stoichiometry and has to equal the solubility constant, the K value of the reaction.  Activity is squared when stoichiometry imposes 2 units of a component. ( your Ag has to be expressed as K=a(Ag)^2*a(SO4) when calculating the ideal activity of Ag aqueous).
