A solution of F is prepared by dissolving 0.0738 + 0.0006 g NaF (molar mass = 41.989 + 0.001 g/mol) in 161.00 ± 0.07 ml 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. F] = M M
