Problem $1.$ If $1\mathrm{.}00lb$ of soda ash $(N{a}_{2}C{O}_3)$ is dissolved in a tank of $80,000$ gallons of water, calculate the concentrations of sodium $(N{a}^{+})$and carbonate $(C{O}_3^{2-})$ in $m\frac{g}{l}$ and mole$/$l$.$ Each mole of soda ash dissociates into one mole of carbonate and two moles of sodium ion.

$N{a}_{2}C{O}_3$longrightarrow$2N{a}^{2+}+C{O}_3^{2-}$
