The amount of i − 3 ( aq ) in a solution can be determined by titration with a solution containing a known concentration of s 2 o 2 − 3 ( aq ) (thiosulfate ion). the determination is based on the net ionic equation 2 s 2 o 2 − 3 ( aq ) + i − 3 ( aq ) ⟶ s 4 o 2 − 6 ( aq ) + 3 i − ( aq ) given that it requires 29.4 ml of 0.380 m na 2 s 2 o 3 ( aq ) to titrate a 30.0 ml sample of i − 3 ( aq ) , calculate the molarity of i − 3 ( aq ) in the solution.

Mike and mitchell decide to have a foot race. they mark off a stretch of 100 yards, and recruit cindy to work the stopwatch. after running the race and looking at the results, cindy declared that mitchell was the fastest. so how did the boys times compare?
