A) when 25.0 ml of a solution of 1.4 x 10-3 m silver nitrate is mixed with 60.0 ml of a solution of 7.5 x 10" m sodium chloride, what is the molar concentration of silver ions in the final mixture? enter answer with 2 significant figures, using "e" for the "x 10" part of your answer, e. g. 2.5 x 10-2 is entered as 2.5e-2.

Lab reagent, hypothesis test. a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl. these six measurements are assumed to be an srs of all possible measurements from solution. they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution. carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
