Chemistry - Concentration Terms Question with Solution | TestHub

The molecular formula of a commercial resin used for exchanging ions in water softening is${\mathrm{C}}_8{\mathrm{H}}_7\mathrm{S}{\mathrm{O}}_3\mathrm{N}\mathrm{a}$$\left(\mathrm{molecular} \mathrm{weight}=206\right)$. What would be the maximum uptake of$\mathrm{C}{\mathrm{a}}^{2+}$ions by the resin if expressed in$\mathrm{mol}$per$\mathrm{gm}$?
