Your instructor has asked you to prepare 2.00 L of 0.169 M NaOH from a stock solution of 53.4 (60.4) wt% NaOH with a density of 1.52 (60.01) g/mL. (a) How many milliliters of stock solution will you need? (b) If the uncertainty in delivering the NaOH is 60.10 mL, calculate the absolute uncertainty in the molarity (0.169 M). Assume negligible uncertainty in the formula mass of NaOH and in the final volume, 2.00 L.
