You prepare a solution by dissolving $0\mathrm{.}050g$ of $)=(111\mathrm{.}1\frac{g}{m}ol$ and $0\mathrm{.}115g$ of $\frac{g}{m}ol)$ with deionized water into a $500mL$ volumetric flask. Assume these salts dissociate completely and no reactions occur $($conservative substances$),$ calculate

a$)$ the ppm concentration of each ionic species

b$)$ the $m\frac{g}{L}$ concentrations of each ion species

c$)$ the mol$/$L concentration of each ionic species

d$)$ the ionic strength of the solution
