6. A chemical engineer makes a dilute hydrochloric acid solution by mixing (1.0±0.2) x 10-6 m³ of 4.5 M HCl solution into 3.10 ± 0.04 L of pure water. For this question, you may treat the initial concentration as being an exact number. a) Assuming that the volume of the final solution is equal to the sum of initial volumes, find the total volume and its uncertainty. Which initial uncertainty dominates the final uncertainty? b) Find the final concentration and uncertainty. Which initial uncertainty dominates the final uncertainty?
