In order to prepare very dilute solutions, a lab technician chooses to perform a series of dilutions instead of measuring a very small mass. a solution was prepared by dissolving 0.360 g of kno3 in enough water to make 500. ml of solution. a 10.0 ml sample of this solution was transferred to a 500.0-ml volumetric flask and diluted to the mark with water. then 10.0 ml of the diluted solution was transferred to a 250.0-ml flask and diluted to the mark with water. what is the final concentration of the kno3 solution? 7.91 Ă— 10-9 m1.42 Ă— 10-4 m5.70 Ă— 10-6 m2.85 Ă— 10-6 m7.12 Ă— 10-3 m
