A solution of $F^{-}$is prepared by dissolving $0\mathrm{.}0879+-0\mathrm{.}0005$gNaF $($molar mass $=41\mathrm{.}989+-0\mathrm{.}001\frac{g}{m}ol)$ in $164\mathrm{.}00+-0\mathrm{.}06mL$ of water. Calculate the concentration of $F^{-}$in solution and its absolute uncertainty.

Significant figures are graded for this problem. To avoid rounding errors, do not round your answers until the very end of your calculations.
